+## 9. Save Ironman:
+ Jarvis is weak in computing palindromes for Alphanumeric characters.
+ While Ironman is busy fighting Thanos, he needs to activate sonic punch but Jarvis is stuck in computing palindromes.
+ You are given a string S containing alphanumeric characters. Find out whether the string is a palindrome or not.
+ If you are unable to solve it then it may result in the death of Iron Man.
+ Example 1:
+ Input : S = "I am :IronnorI Ma, i"
+ Output : YES
+ Explanation: Ignore all the symbol and whitespaces S = "IamIronnorIMai". Now, Check for pallandrome ignoring uppercase and lowercase english letter.
