this will be the correct rearrangement

#include <stdio.h>
#include <string.h>

int main() {
    int T, N;
    char S[100];  
    scanf("%d", &T);

    while (T--) {
        scanf("%d", &N);
        scanf("%s", S);

        for (int i = 0; i < strlen(S); i += 2) {
            if ((S[i] == '0') && (S[i + 1] == '0'))
                printf("A\n");
            if ((S[i] == '0') && (S[i + 1] == '1'))
                printf("T\n");
            if ((S[i] == '1') && (S[i + 1] == '0'))
                printf("C\n");
            if ((S[i] == '1') && (S[i + 1] == '1'))
                printf("G\n");
        }
    }

    return 0;
}
