HI @cbcao263 , you don;t have to restrict the number explicitily as constraints gives us the idea on how large the values can be so accordingly we can devise the algorithm . now coming to your implementation you are taking input as integer array so for input like say, 441 it will store it in arr[0] but won;t take any input for another values for array . i would recommend to take input as long long .

you will get the idea on how to take the input
