Asked in companies
You are given a string 'S'. Your task is to check whether the string is palindrome or not. For checking palindrome, consider alphabets and numbers only and ignore the symbols and whitespaces.
Note :
String 'S' is NOT case sensitive.
Example :
Let S = “c1 O$d@eeD o1c”.
If we ignore the special characters, whitespaces and convert all uppercase letters to lowercase, we get S = “c1odeedo1c”, which is a palindrome. Hence, the given string is also a palindrome.
Problem approach
Step 1 : I first applied bubble sort. It was not good enough.
Step 2 : Interviewer asked me to optimise the solution.
Step 3 : Then i gave solution with merge sort and interviewer was happy.
