#include <stdio.h> 
 
int main() { 
    int t; 
    scanf("%d", &t); 
    while (t--) { 
        long long n; 
        scanf("%lld", &n);
      	if (n==1){
        	printf("1\n");
            continue;
        }
        long long m = 1; 
        while (m <= n) m <<= 1; 
        printf("%lld\n", m); 
    } 
    return 0; 
}
