If it is greater than both of its neighbours, then return the element, it is a peak. If the right element is greater, then find the peak recursively in the right side of the array. WebIn other words, peak can’t be the first or last element in the mountain array. int climb = 0 while (climb < n - 1 && X[climb] < X[climb + 1]) climb = climb + 1 if (climb == 0 climb == n - 1) return false If peak is present at some middle element, we run another loop from that position to check strictly decreasing order or elements. aeria aimatos
