Coding problem1
1. Check if a String is a Palindrome in JavaScript
Write a JavaScript program that takes a string input from the user and checks whether it is a palindrome. A palindrome is a string that reads the same forwards and backwards. The program should ignore case and non-alphanumeric characters when performing the check and output whether the string is a palindrome or not.
Problem approach
- Create a function named isPalindrome that takes a string as a parameter.
- Initialize two variables: start = 0 and end = string.length - 1 to point to the first and last characters of the string.
- Declare a boolean variable isPalindrome = true.
- Use a loop to iterate through the string, comparing characters from both ends.
- Inside the loop, if the characters at start and end are not equal, set isPalindrome = false and break the loop.
- After each comparison, increment start and decrement end.
- Once the loop finishes, return the value of isPalindrome.
