Given a linear antenna array with an excitation distribution affording an optimal sum pattern, subarray weighting allows the same array also to generate a difference pattern, with minimal alteration of the signal feed circuitry. In this approach, it is not necessary to consider the whole array for...
So, we will sum-up all the no of subarrays with odd 1s for each bit (saysumisumi). so our answer would be∑sumi∗2i∑sumi∗2i. here2i2iis the contribution ofithith
Learn how to find the largest sum of subarrays in JavaScript with step-by-step examples and explanations.
Given an integer array nums and two integers firstLen and secondLen, return the maximum sum of elements in two non-overlapping subarrays with lengths firstLen and secondLen. The array with length firstLen could occur before or after the array with length secondLen, but they have to be non...
