@rohanbhat
I have rectified it . U don’t need this much conditions .
I have made some things easier . Hope u will get the logic.

#include <stdio.h>

int main(void) {
	// your code goes here
	int test;
	scanf("%d", &test);
	while(test--){
	    int size;
	    scanf("%d", &size);
	    char arr[size];
	    scanf("%s", arr);
	    int counter1=0,counter0=0;
	    for(int i=0;i<size;i++){
	        if(arr[i]=='0') counter0++;
	        if(arr[i]=='1') counter1++;
	    }
	    if(counter1<=counter0)
	    {
	        printf("%d\n",counter1);
	    }
	    else
	    {
	        printf("%d\n",counter0+1);
	    }
	}
	return 0;
}
