  • Difficulty Level : Basic
  • Last Updated : 09 Sep, 2021

A string is given, and you have to find all the words (substrings separated by a space) which are greater than the given length k.

Examples:

Input : str = "hello geeks for geeks 
          is computer science portal" 
        k = 4
Output : hello geeks geeks computer 
         science portal
Explanation : The output is list of all 
words that are of length more than k.

Input : str = "string is fun in python"
        k = 3
Output : string python 

The idea is to first split given string around space. Then traverse through all words. For every word, check

C++




// C++ program to find all string
// which are greater than given length k
 
#include <bits/stdc++.h>
using namespace std;
 
// function find string greater than
// length k
void string_k(string s, int k)
{
    // create the empty string
    string w = "";
    // iterate the loop till every space
    for(int i = 0; i < s.size(); i++)
    {
        if(s[i] != ' ')
         
            // append this sub string in
            // string w
            w = w + s[i];
        else {
             
            // if length of current sub
            // string w is greater than
            // k then print
            if(w.size() > k)
                cout << w << " ";
                w = "";
        }
