查找大于给定长度 k 的单词

给定一个字符串，你必须找到所有大于给定长度 k 的单词（用空格分隔的子字符串）。

例子：

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

这个想法是首先在空间周围分割给定的字符串。然后遍历所有单词。对于每个单词，检查

C++

// C++ program to find all string
// which are greater than given length k
 
#include 
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 = "";
        }
    }
}
 
// Driver code
int main()
{
    string s = "geek for geeks";
    int k = 3;
    s = s + " ";
    string_k(s, k);
    return 0;
}
