Peak element in array python
WebFind peaks inside a signal based on peak properties. This function takes a 1-D array and finds all local maxima by simple comparison of neighboring values. Optionally, a subset of these peaks can be selected by specifying conditions for a peak’s properties. Parameters: xsequence A signal with peaks. heightnumber or ndarray or sequence, optional WebLeetCode – Find Peak Element. A peak element is an element that is greater than its neighbors. Given an input array where num [i] ≠ num [i+1], find a peak element and return its index. The array may contain multiple peaks, in that case return the index to any one of the peaks is fine. You may imagine that num [-1] = num [n] = -∞.
