Problem Statement

Problem Statement

You are given a list of int values. We wish to find the sum of these values, however we want to ignore duplicates. Return the sum of the unique values in the list.

Constraints

  • values will contain between 1 and 50 elements, inclusive.
  • Each element of values will be between 1 and 100, inclusive.
Examples
0)
{ 1, 2, 3, 4, 5 }
Returns: 15

The values are all unique, so we return 1 + 2 + 3 + 4 + 5 = 15.

1)
{ 1, 2, 3, 4, 3 }
Returns: 10

The value 3 is duplicated, so we only count it once. 1 + 2 + 3 + 4 = 10.

2)
{ 1, 1, 1, 1, 1, 1, 1, 1, 1 }
Returns: 1
3)
{ 18, 22, 9, 1, 7, 18, 13, 49, 13, 9, 49, 49, 7 }
Returns: 119
4)
{ 1 }
Returns: 1
