My issue

Why I will getting runtime error even I solved it

My code

#include <stdio.h>
#include<string.h>
void main()
{
    int t,n,i;
    char s[100];
    scanf("%d",&t);
    while(t--)
    {
        scanf("%d",&n);
        scanf("%s",&s);
        for(i=0;i<strlen(s);i+=2)
        {
        if((s[i]=='0') && (s[i+1]=='0')) 
        printf("A");
        if((s[i]=='0') && (s[i+1]=='1'))
        printf("T");
        if((s[i]=='1') && (s[i+1]=='0'))
        printf("C");
        if((s[i]=='1') && (s[i+1]=='1'))
        printf("G");
        }
        printf("\n");
    }
    return 0;
}

the max size of the character array would be 1000 instead of 100.

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

void encodeSequence(char binaryString, int length) {
for (int i = 0; i < length; i += 2) {
if (binaryString[i] == ‘0’ && binaryString[i + 1] == ‘0’) {
printf(“A”);
} else if (binaryString[i] == ‘0’ && binaryString[i + 1] == ‘1’) {
printf(“T”);
} else if (binaryString[i] == ‘1’ && binaryString[i + 1] == ‘0’) {
printf(“C”);
} else if (binaryString[i] == ‘1’ && binaryString[i + 1] == ‘1’) {
printf(“G”);
}
}
printf(“\n”);
}

int main() {
int T, N;
scanf(“%d”, &T);

for (int t = 0; t < T; t++) {
    scanf("%d", &N);

    char binaryString[N + 1];
    scanf("%s", binaryString);

    // Ensure the input string length is even
    if (strlen(binaryString) != N) {
        printf("Invalid input. Length mismatch!\n");
        return 1;
    }

    encodeSequence(binaryString, N);
}

return 0;
