content: /*
  Given a string, determine if it is a palindrome, considering only alphanumeric characters.
  A palindrome is a word, number, phrase, or other sequences of characters which read the same backwards and forwards.
  Example:
  If the input string happens to be, "malayalam" then as we see that this word can be read the same as forward and backwards, it is said to be a valid palindrome.
  The expected output for this example will print, 'true'.
  From that being said, you are required to return a boolean value from the function that has been asked to implement.
  
  Input Format:
  The first and only line of input contains a string without any leading and trailing spaces. All the characters in the string would be in lower case.
  Output Format:
  The only line of output prints either 'true' or 'false'.
  Note:
  You are not required to print anything. It has already been taken care of.
  
  Constraints:
  0 <= N <= 10^6
  Where N is the length of the input string.
  Time Limit: 1 second
  
  Sample Input 1 :
  abcdcba
  Sample Output 1 :
  true 
  
  Sample Input 2:
  coding
  Sample Output 2:
  false
