Count Spikes

Count Spikes is an Amazon coding interview problem. Given an array of prices and an integer k, count how many indices are k-Spikes. An index i is a k-Spike when at least k elements before i are strictly less than prices[i] and at least k elements after i are strictly less than prices[i]. Return the total count of such elements. This interview question from Amazon focuses on identifying positions that dominate enough smaller values on both sides.
