class Solution { public boolean isMonotonic(int[] A) { boolean increasing = true; boolean decreasing = true; for (int i = 0; i < A.length - 1; ++i) { if (A[i] > A[i+1]) increasing = false; if (A[i] < A[i+1]) decreasing = false; } return increasing || decreasing; } }
Can anyone please explain how the return value is working.

Answer
increasing || decreasing
means increasing OR decreasing
. If either variable is true
then the whole method will return true
, otherwise it will return false
.
||
is the logical OR operator.
