Statement
Given a number n, the function, add all the multiples 3 and 5 in the range [1, n).
Example:
Say, n <- 10
In the range [1, 10):
- multiples of
3are3,6and9.3 + 6 + 9 = 18
- There's only one multiple of
5which is5itself, as we are only supposed to count from1ton - 1.
Total sum is 18 + 5 = 23.
Note: if a number is a multiple of both 3 and 5, it should be added only once.
Input:
10
Output:
23
