   void main() {

      for (i = 0; i < 10; i++) { //Calcolo quadrati "base"
         square[i] = i * i;
      }

      mem[1]=2;

		scanf( "%lld", &k );
      count=k;
     

		for (i=1; i<=count; i++) {
			scanf( "%lld", &k );
			res = isHappy(sum_cifre(k));
			printf( "Case #%lld: ", i );
			if (res==2) {
				printf( "%lld is a Happy number.\n", k );
         }
			else {
				printf( "%lld is a Unhappy number.\n", k );
         }

You should get RTE not WA because of this

Code: Select all

int arr[2000];
............
..........
if(arr[n]==1)
...............

where n can be much bigger than 2000.
