Added: 2026-06-06

[00:00:00]Assalamu Alaikum everyone. How are you all? I am fine. Today the Federal Board Class 12 Computer Science PBA has been held.

[00:00:07]Well, that is the solution, we have brought the complete solution of the entire PBA for you people.

[00:00:13]Well, first of all, this PBA of yours, that is, its solution, has been prepared by our beloved Sir Sabahat. He deserves the credit for taking out so much time and solving your entire PBA paper. Let's move on to our solution. In this, each and every question is solved by you people. First of all Sir Sabha, thank you so much. After this we had Section A of 30 marks, in which Part A of Question One was Python Function Greatest of Three Numbers. He was worth five marks.

[00:00:46]What was the question in this? Write a Python program using a function to find and display the greatest of three numbers.

[00:00:52]In this you had to write this entire like program. It would have been yours. Note that the function uses logical AND and AND conditions to compare all three numbers. It takes three parameters and returns the greatest value. You guys can see this. This is your solution. Now reading each one and telling each one, then it becomes a very long video. That's why children get bored.

[00:01:14]So we move ahead. Question number one part B which is food delivery app MVP analysis. It tells you what you are. In this you had to do this first and you would have had this answer. Meaning that you had to write the answer related to this. The second was Suitable Tools Technology. You guys should have done this. Talking about the front end and back end. You should have told me in the front end. This is created for you and on the back end you get your answer. Number three which is three future improvements after MVP. So you have this, this, this and this. After this question one a and python program tried countries ah to file. The answer is to develop a Python program that creates a file named.txt and writes the names of three countries in it. This is the answer you have.

[00:02:00]Like this is the kind of answer you had written.

[00:02:03]Wrote a program like this. So you would have got your full marks.

[00:02:07]After this, there is your question one part and feedback on the job finder prototype. Here is a feedback on the job finder app prototype. After this your answer should have been like this. You had to give your answer and your marks would have been confirmed.

[00:02:23]You guys can check this. You can pause the video and check. Ok? After this you had question number two of 10 marks.

[00:02:30]A teacher keeps track of students' marks out of 100. Marks you had givens. What did you have to do?

[00:02:38]Number two of part two is store and print marks list you had given.

[00:02:42]You should have done this first of all. You should write this program as shorts program.

[00:02:46]After this, you had to write the output of maximum and minimum, what are the maximum marks and what are the minimum marks of all these students. After this, Part C of Question Number Two was Identify and Correct Errors in Code. You had to correct and find the errors that you had. You saw this error. Semi callan it comes to you and it's done. You have written the correct code.

[00:03:11]After this, part D of question number two which is modified code count students scoring less than 50 the original ah code count students with marks ah is less is greater than and equal to 70 modified to count students scoring less than 50 you had less than 50 which was 50 means it was equal to 50 you had to write that program then this would have been your program and a perfect scene would have been created.

[00:03:34]After this you had part 10 of question number three.

[00:03:35]A question number three, sorry, that was yours worth 10 marks.

[00:03:40]In this you had a question given, part one of question number three. This was Check If Single Student Issued a Book. You will get this Book Issued Book Not Issued. This is a simple if else program. And after this, the record book issued status for five students. You had to write that for these five students.

[00:03:59]You had to do it by using the string string of Ah F.

[00:04:01]Part three of question number three which is print total number of students who issued books, you had to write this program and this would have been yours.

[00:04:09]Part four of question number three which is calculate and print percentage of students who issued books, you have this program's answer. After this, part A of section B, section B was of 20 marks, your question four was of six marks, part algorithm check positive and negative number, you had to write this algorithm and in this you had to write the algorithm to identify positive and negative number, you had to write how to write, you had to make steps, you had to write it, you would have done it, you can watch by pausing the video because then the video becomes too long.

[00:04:41]Question Four Part B Binary Search Ah for 89 in List Three This was a question of marks.

[00:04:45]You had the list you had given. The list has nine elements, you had to do this and you would have had this entire table type created. The conclusion 89 is found at index seven in three passages and you had the given pseudo code to print odd numbers from one to 50. You had to write the pseudo code and you would be done.

[00:05:05]After this, you had to do part B of question four and trace table for factorial pseudo code.

[00:05:10]Pseudo code computes 5sorial n = 5sorial starts at one. If you had done this entire solution, your work would have been done.

[00:05:20]After this, your Simplify Question Five is Simplify Boolean Function Using Map and Construct Logic Circuit in 4 + 2, which means this is worth six marks. You had this logic circuit you had given. You had to make a chem map. This is the map of step one, you had to do this and here you have the solution. You guys can check. Here I will show you guys. The whole of it would have been yours. You guys can check this.

[00:05:47]After this, step two you had to do the group once you did this. Do the grouping.

[00:05:51]Group One Group Two. There you have it: the simplified expression f = b + ac.

[00:05:58]After this, step three was the logic circuit for f = b + ac. This is the simplified expression you have.

[00:06:06]After this [sound of clearing throat] whatever you have, you should have checked here so that it becomes completely yours. Ok?

[00:06:14]After this let us move on to question number six.

[00:06:16]Eight Marks' Python program was to plot a line chart for y = 3x + 4. Well, you had to do this program like this.

[00:06:26]You mean this program had to be written like this.

[00:06:28]Your program will be like this in Python. You first imported it and used its library. Generate Data Set You created a data set. After that, you have the complete given. You guys can check it here. Then it will be perfect. After this, Part One of Part B of Question Six.

[00:06:46]Interview questions. Teachers' Perspectives on Digital Tools. Ah qualitative interview questions for ah teachers about digital tools in classroom teaching. This would have been your answer. You should have done this.

[00:06:58]After that, you had to answer Part B of Question Six, Part Two, which is Questionnaire Students Exercise and Physical Activity Habits, and this would have been your entire answer.

[00:07:11]So this was our video for today. Hope you guys liked the video and your PBA must have been the best because Mac prepared you guys by changing your thinking, so change your thinking, whenever Mac prepares the children, they always score full marks, we will meet you in our next video, take care of yourself, definitely subscribe to the channel because your next paper is of Physics, its free one shot classes will be on this YouTube channel Soch Balomi Math, so quickly subscribe to the channel, like the video and share it with friends, we will meet you in our next video, take care of yourself, remember me in your prayers, please allow me.
