Very nice explanation sir thankyou so much 🙏🏼🙏🏼🙏🏼
But in split() method, why two or more last spaces of String are removed
Please explain sir how splits method exactly works.

class Solution {
public int lengthOfLastWord(String s) {
int n = s.length();
while (n > 0 && s.charAt(n - 1) == ' ') n--;
int i = n - 1;
int count = 0;
while (i >= 0 && s.charAt(i) != ' ') {
count++;
i--;
}
return count;
}
}
