Most Simple C++ Solution (With Split-like feature of Python)

sohammehta

This solution uses all inbuilt methods of cpp to make life simple.

First being strtok which takes char* as input and splits it with the delimiter we provide Check the Method here

Next we need to convert our string to char* so we use .c_str() function. However, it porivdes const char* hence we use strdup().

class Solution {
public:
    int lengthOfLastWord(string s) {
        
        int ans = 0;
        
        char *token = strtok(strdup(s.c_str()), " "); //Converting the string to char* and then making it mutable

        while(token!=NULL)
        {
            string str(token); //Converting char* to String 
            
            ans = str.size();

            token=strtok(NULL, " ");
 
        }

        return ans;
    }
};
