#include<bits/stdc++.h>
using namespace std;
int main(void) {
	string word,key;
	cin>>key;
	cin>>word;
	int ks=key.size();
	for(int i=0; i<word.size(); i++) {
		cout<<(int)word[i]<<' '<<(int)key[i%ks]<<' ';
		if(word[i]<'a'&&word[i]>='A') {
			if(key[i%ks]>'a') word[i]-=key[i%ks]-'a';
			else word[i]-=key[i%ks]-'A';
			if(word[i]<'A') word[i]+=26;
		}
		if(word[i]>='a') {
			if(key[i%ks]>'a') word[i]-=key[i%ks]-'a';
			else word[i]-=key[i%ks]-'A';
			if(word[i]<'a') word[i]+=26;
		}
		cout<<(int)word[i]<<endl;
	}
	cout<<endl;
	cout<<word;
	return 0;
