My issue

My code

#include <stdio.h>

int main() 
{
    int t;
    scanf("%d", &t);
	
    while (t--)
    {
        int X;
        scanf("%d", &X);

        if (X % 10 == 0)
        {
            printf("\n0");
        }
        else
        {
            int found = 0;
            for (int i = 1; i <= 5; i++)
            {
                if ((X * i) % 10 == 0)
                {
                    printf("\n%d", i);
                    found = 1;
                    break;
                }
            }

            if (!found)
            {
                printf("\n-1");
            }
        }
    }
    return 0;
}

the logic is not right u can only multiply it with 2
so if the number is divisible by 5 then only one turn needed or else if the number is already divisible by 10 then 0 needed else print -1;

I mistakenly overlooked the multiplication component.
Despite incorporating your suggested logic into my code, it is still producing an incorrect answer.

// Update the code below to solve the problem

#include <stdio.h>

int main() 
{
	int t;
    scanf("%d",&t);
	
	while(t--)
	{
	    int X;
	    scanf("%d",&X);
	    if(X%10==0)
	    printf("0\n");
	    else if(X%5==0)
	    printf("1\n");
	    else
	    printf("-1\n");
	}
}

its working perfectly fine please check your code again
