#include<stdio.h>
int main(void) {
	char a[101], b[101];
	scanf("%s %s", a, b);
	char s[1000];
	int cnt = 0;
	for (int i = 0; b[i] != '\0'; i++) {
		s[i] = b[i];
		cnt++;
	}
	for (int i = 0; a[i] != '\0'; i++) {
		s[cnt] = a[i];
		cnt++;
	}
	for (int i = 0; i < cnt; i++) {
		printf("%c", s[i]);
	}
	printf("\n");
	return 0;
