WebMar 3, 2016 · 3 Answers. Yes there is a O (n lgn) algorithm if all elements are non-negative. For each i: Binary search maximum j such that p [j] - p [i-1] <= k, add j-i+1 to the counter. Why it works, is because for each i, we are trying to find the maximum range starting from i such that the sum of this range is <= k. WebApr 29, 2024 · Subarray Product Less Than K in C++.

WebThen keep moving the right endpoint and keep multiplying the new elements. Each time you are able to do so without exceeding K, increase ctr. Now, if the product exceeds K, then start shifting the left endpoint and divide the product that you had, with the element the left endpoint is processing, until the product again becomes lesser than K. WebFeb 2, 2015 · We can use a balanced binary search tree for this purpose. Here is a pseudo-code of this solution: tree = an empty search tree result = 0 // This sum corresponds to an empty prefix. prefixSum = 0 tree.add (prefixSum) // Iterate over the input array from left to right. for elem <- array: prefixSum += elem // Add the number of subarrays that have ...
WebAnswer (1 of 5): If the numbers are all positive integers, then you can use the sliding window technique to find the number of subarrays whose product is less than D. You can think of a sliding window as a slice of the array with a left index and a right index. For this specific problem, we mai...
