Solution

/* This Program counts the distinct words in the input
string preceded each word by its count */


#include <stdio.h>
#include <string.h>

void DistinctWords(char s[ ]);

string\n");
else

/* Purpose: This function counts the distinct words in the
input string preceded each word by its count
Input : String
Output : distinct words with its count
