#include <iostream>
#include <vector>
#include <iomanip>
#include <string.h>
#include <string>
#include <algorithm>
using namespace std;
bool strEqual(const string& str1, const string& str2)

});
}
unsigned GetWordFrequency(vector<string>& vec,const string& str)
{
//return the number of occurrences of the search word in the
unsigned res=0;//the numbers of occurences
for(auto itr:vec)
