Shell script to check an input number is palindrome or not palindrome : Solved with Algorithm

Problem Statement

Write a shell script to check a number palindrome or not

Algorithm

Step 1 : Start
Step 2 : Display “Enter a Number”
Step 3 : read n
Step 4 : temp ← n
Step 5 : Repeat step 6 to 9
While temp> 0
Step 6 : ans ← ans*10
Step 7 : mod ← temp%10
Step 8 : ans ← ans+mod
Step 9 : temp ← temp/10
Step 10: If n = ans then
i. Display “It&’s a Palindrome Number”
Step 11: else
i. Display “It’s not a Palindrome Number”
Step 12: Stop
