He had spent the last three months ignoring the book. "Too bulky," he'd say. "Too many examples." Now, the bulky book was his only hope.

Instead of reading the solution, he forced himself to write code. He failed the first time (forgot to convert to lowercase). Failed the second time (indentation error). On the third attempt, it worked.

Meera didn't pick up the book. Instead, she picked up a marker and drew a big box on his whiteboard. "This is your main program." Then she drew a smaller box inside. "This is your function."

He turned to . Sumita Ma'am's table compared Stack vs Queue with real-life examples: "Plates in a cafeteria" for LIFO. He coded push() and pop() in 15 minutes.

Implement a stack using a list.

Write a program to check if a string is a palindrome. Instead of reading the solution, he forced himself

The examiner nodded. "Good. Clear." Rohan scored 95/100 in Computer Science. Later, a junior asked him, "Which book is best for Class 12 CS?"

Rohan stared at the blinking cursor on his screen. It was 11:30 PM. The Computer Science practical exam was in 10 hours. His Sumita Arora textbook lay open at Chapter 3: Working with Functions , but the pages might as well have been written in ancient Greek.
