Peak Signals in Modified Array

Question

You are given an array of integers `signalStrengths`. Modify the array by replacing each signal strength with the product of its neighboring signals. For edge signals, consider only the existing neighbor. Identify the indices of peak signals in the modified array, where a peak signal is one that is not weaker than its neighbors.

DSAMaster · Accepted Answer

To optimally solve the Peak Signals in Modified Array problem involving Arrays, it is important to analyze constraints. Time Complexity: O(n), Space Complexity: O(n). Using a more efficient approach involves iterating over the array and modifying each element based on the product of its neighboring signals. This allows for a constant amount of work to be done for each element, resulting in a time complexity of O(n).
