Task: Jarvis is week 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. Given a string S containing alphanumeric characters. Find out whether the string is a palindrome or not. If string is palindrome print "YES" else print "NO". Iron Man life is in your hands now. Example: Input: 1 Ab?/Ba Output: YES Here is the Code: Program in C++: #include<iostream> using namespace std; string saveIronMan(string s) { int n = s.length(); for(int i=0;i<n;i++) { if(isalpha(s[i])) s[i]=toupper(s[i]); } int i=0,j=n-1; while(i<j) { while(!isalpha(s[i])&&!isdigit(s[i])) { if(i<n) i++; } while(!isalpha(s[j])&&!isdigit(s[j])) { if(j>-1) j--; } if(s[i]!=s[j]) { return "NO"; } i
