# Length of Last Word Problem Solution

Length of Last Word Problem: Given a string `s` consisting of words and spaces, return the length of the last word in the string.

A word is a maximal substring consisting of non-space characters only.

Example :

```Input: s = "Hello World"
Output: 5
Explanation: The last word is "World" with length 5.```

## Problem Solution In Python

``````class Solution:
def lengthOfLastWord(self, s):
"""
:type s: str
:rtype: int
"""
return len(s.rstrip().split(' ')[-1])
``````

## Problem Solution In Java

``````class Solution {
public int lengthOfLastWord(String s) {
s = s.trim();
return s.length() - s.lastIndexOf(" ") - 1;
}
}
``````

## Problem Solution In C++

``````class Solution {
public:
int lengthOfLastWord(string s) {
stringstream ss(s);
string word;
while(ss >> word) {
}
return word.size();
}
};
``````

## Problem Solution In C

``````int lengthOfLastWord(string s)
{
string k;
int count  = 0;
int len = 0 ;
for (int i = 0; i < s.length(); i++)
{
if (s[i] != ' ')
{
count++;
len = count;
}
else
{
count = 0;
if (len < count)
{
len = count;
}
}
}
return len;
}
