Ip Sumita Arora Class 12 Direct

Write a program to check if a string is a palindrome.

His older sister, Meera, a college coder, peeked into his room. "Still stuck?"

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. ip sumita arora class 12

By 2:00 AM, Rohan had solved 12 programming problems. The thick book was no longer a monster—it was a tool . Every concept had an example. Every example had an edge case explained. Every chapter ended with a debugging section that anticipated his exact mistakes.

"It's not magic," he said. "But it's the most patient teacher. It doesn't assume you know anything. It fails with you, then teaches you why you failed, then shows you how to succeed. Just don't wait until 11:30 PM the night before." Sumita Arora’s book isn’t just for reading—it’s for doing. The unsolved exercises, the margin notes, and the debugging questions are where the real learning happens. Don't skip them. Write a program to check if a string is a palindrome

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.

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. It was 11:30 PM

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?"
