apcsaLoopsAddExclusive


Given two ints a and b, add all the numbers between a and b, exclusive. So if a is 4 and b is 7, the result should be 11, the result of 5+6. For all inputs, a < b is a precondition (a is guaranteed to be less than b for all inputs).


apcsaLoopsAddExclusive(4, 7) → 11
apcsaLoopsAddExclusive(5, 8) → 13
apcsaLoopsAddExclusive(-10, -4) → -35

...Save, Compile, Run (ctrl-enter)

public int apcsaLoopsAddExclusive(int a, int b) { }
