Java > Warmup-1 >diff21 (CodingBat Solution)

Problem:

Given an int n, return the absolute difference between n and 21, except return double the absolute difference if n is over 21.

diff21(19) → 2
diff21(10) → 11
diff21(21) → 0

Solution:

public int diff21(int n) {
int OUTPUT = 0;
  if (n > 21)
     OUTPUT = Math.abs((21 - n)*2);
     else OUTPUT = Math.abs(21 - n);
     return OUTPUT;
}
