You are given an integer n.
The score of n is defined as the sum of d * freq(d) over all distinct digits d, where freq(d) denotes the number of times the digit d appears in n.
Return an integer denoting the score of n.
Example 1:
Input: n = 122
Output: 5
Explanation:
1 * 1 = 1.2 * 2 = 4.n is 1 + 4 = 5.Example 2:
Input: n = 101
Output: 2
Explanation:
0 * 1 = 0.1 * 2 = 2.n is 2.Constraints:
