Given two strings
Examples:
Input : fighter warrior Output :warhter figrior Input :remuneration day Output :dration remuneay
In the first example, fighter is made up of two parts fig and hter. Similarly, warrior is also made up of two parts war and rior. Interchange the first part of both the strings to create two new strings warhter and figrior. Similarly, in the second example first part of remuneration which is remune is exchanged with the first part of day to create dration and remuneay.
Implementation:
// CPP code to create two new strings // by swapping first and second halves #include<bits/stdc++.h> using namespace std;
// Function to concatenate two // different halves of given strings void swapTwoHalves(string a , string b)
{ int la = a.length();
int lb = b.length();
// Creating new strings by
// exchanging the first half
// of a and b. Please refer below for
// details of substr.
string c = a.substr(0, la/2) +
b.substr(lb/2, lb);
string d = b.substr(0, lb/2) +
a.substr(la/2, la);
cout << c << endl << d << endl;
} // Driver function int main()
{ string a = "remuneration" ;
string b = "day" ;
swapTwoHalves(a, b);
