Index Of Ek Chalis Ki Last Local Online

# Example usage: arr = [3, 1, 4, 1, 5, 9, 2, 6] last_max_index = find_last_local_extremum(arr) last_min_index = find_last_local_extremum(arr, find_max=False)

Here is a simple Python function to find the last local maximum or minimum in an array:

try: return last_extremum_index except UnboundLocalError: return None index of ek chalis ki last local

This should help you find the last local maximum or minimum in an array of 40 elements or any size. Adjust the find_max parameter to switch between finding local maxima and minima.

print(f"Last local maximum index: {last_max_index}") print(f"Last local minimum index: {last_min_index}") This function works by iterating through the array, checking each element to see if it's a local maximum or minimum based on the find_max parameter. The index of the last local extremum found is returned. The function also handles edge cases for the first and last elements. If no local extremum is found, the function returns None . # Example usage: arr = [3, 1, 4,

Returns: int or None: The index of the last local extremum. If no local extremum is found, returns None. """ # Iterate over the array from the second element to the second last element for i in range(1, len(arr) - 1): if find_max and arr[i] > arr[i-1] and arr[i] > arr[i+1]: # Found a local maximum, update and continue last_extremum_index = i elif not find_max and arr[i] < arr[i-1] and arr[i] < arr[i+1]: # Found a local minimum, update and continue last_extremum_index = i

# Check the first and last elements if find_max: if len(arr) > 1 and ((arr[0] > arr[1] and i != 0) or (arr[-1] > arr[-2] and i != len(arr) - 1)): last_extremum_index = 0 if arr[0] > arr[1] else len(arr) - 1 else: if len(arr) > 1 and ((arr[0] < arr[1] and i != 0) or (arr[-1] < arr[-2] and i != len(arr) - 1)): last_extremum_index = 0 if arr[0] < arr[1] else len(arr) - 1 The index of the last local extremum found is returned

Parameters: arr (list): The input array. find_max (bool): If True, find the last local maximum; otherwise, find the last local minimum.
