#include <stdio.h>
#include <ctype.h>

void my_strcpy(char *dest, char *src) {
    while (*src != '\0') {
        *dest = *src;
        dest++;
        src++;
    }
    *dest = '\0';
}

int main() {
    int n;
    char w[100], copy[100];
    scanf("%d", &n);
    for (int i = 0; i < n; i++) {
        scanf("%s", w);
        my_strcpy(copy, w);
        for (int j = 0; copy[j] != '\0'; j++) copy[j] = toupper(copy[j]);
        printf("%s\n", copy);
    }
    return 0;
}
