Problem Statement

Given are 1-digit positive integers a and b. Consider these two strings: the concatenation of b copies of the digit a, and the concatenation of a copies of the digit b. Which of these is lexicographically smaller?

Constraints

1 \leq a \leq 9

1 \leq b \leq 9

a and b are integers.

Input

Input is given from Standard Input in the following format:

a b

Output

Print the lexicographically smaller of the two strings. (If the two strings are equal, print one of them.)

Sample Input 1

4 3

Sample Output 1

3333

We have two strings 444 and 3333. Between them, 3333 is the lexicographically smaller.

Sample Input 2

7 7

Sample Output 2

7777777

Solution in C (GCC 5.4.1) (judge verdict: Wrong Answer)

#include<stdio.h>
#include<string.h>
int main()
{
    int a,b;
    scanf("%d%d",&a,&b);
    char s1[15],s2[15];
    int i,j;
    for(i=0;i<a;i++)
        s1[i]=b+'0';
    s1[i]='\0';
    for(i=0;i<b;i++)
        s2[i]=a+'0';
    s1[i]='\0';
    if(strcmp(s1,s2)<=0) printf("%s",s1);
    else printf ("%s",s2);
    return 0;
}
