#include<iostream>
#include<string.h>
using namespace std;
int main()
{
	char first[30];
	char second[30];
	 int k;
	 int l;
     int flag=0;
	cout<<"plz enter first string: ";
	cin>>first;
	cout<<"plz enter 2nd string : ";
	cin>>second;
	k=0;
	 l=0;
	while (first[k]!='\0')
	{
		k++;
	}
	while(second[l]!='\0')
