Given an integer number n
, return the difference between the product of its digits and the sum of its digits.
Example 1:
Input: n = 234 Output: 15 Explanation: Product of digits = 2 * 3 * 4 = 24 Sum of digits = 2 + 3 + 4 = 9 Result = 24 - 9 = 15
Example 2:
Input: n = 4421 Output: 21 Explanation: Product of digits = 4 * 4 * 2 * 1 = 32 Sum of digits = 4 + 4 + 2 + 1 = 11 Result = 32 - 11 = 21
Constraints:
1 <= n <= 10^5
class Solution { public int subtractProductAndSum(int n) { int res = 0; int pro = 1, sum = 0; if(n == 0) return res; while(n != 0){ int d = n % 10; pro *= d; sum += d; n /= 10; } return pro - sum; } }
