Abstract: Sparse arrays designed based on fourth-order difference co-array (DCA) can achieve significantly higher uniform degrees-of-freedom (uDOFs). However, most existing fourth-order sparse arrays ...
# Given an array of positive integers arr, return the sum of all possible odd-length subarrays of arr. # A subarray is a contiguous subsequence of the array.
Abstract: Recently, numerous design schemes for high-order sparse linear arrays (SLAs) have been introduced for underdetermined direction-of-arrival (DOA) estimation based on high-order cumulants, ...
Community driven content discussing all aspects of software development from DevOps to design patterns. The prefix sum problem in computer science is a popular programming puzzle used to test the ...
Given an integer array nums and an integer k, return true if nums has a continuous subarray of size at least two whose elements sum up to a multiple of k, or false otherwise. An integer x is a ...
Various modern applications of computer science and machine learning use multidimensional datasets that span a single expansive coordinate system. Two examples are using air measurements over a ...
