Number of Segments in a String in C++
Suppose we have a string s. We have to count the number of segments in a string, where a segment is defined to be a contiguous sequence of characters (no whitespace).
So, if the input is like "Hello, I love programming", then the output will be 4, as there are 4 segments.
To solve this, we will follow these steps −
n := 0
for initialize i := 0, when i < size of s, update (increase i by 1), do −
if s[i] is not equal to white space, then −
(increase n by 1)
while (i < size of s and s[i] is not equal to white space), do −
(increase i by 1)
return n
Example
Let us see the following implementation to get a better understanding −
#include <bits/stdc++.h>
using namespace std;
class Solution {
public:
int countSegments(string s) {
int n = 0;
for(int i = 0; i < s.size(); i++){
if(s[i] != ' ')
n++;
while( i < s.size() && s[i] != ' ')
i++;
}
return n;
}
};
main(){
Solution ob;
cout << (ob.countSegments("Hello, I love programming"));
}Input
"Hello, I love programming"
Output
4
