An array is not useful in places where we have operations like insert in the middle, delete from the middle, and search in unsorted data. If you only search occasionally: Linear search in an array or ...

Abstract: With the advancement of monopulse radar technology, synthesis of the sum-and-difference patterns (SDPs) for the radome-enclosed arrays has emerged as a pressing area of research. Due to the ...

Arrays are a popular data structure used in programming for storing multiple values of the same data type. Often times, when working with arrays, we may want to find the sum of all the elements in the ...

You have been given an integer array/list(ARR) and a number 'num'. Find and return the total number of pairs in the array/list which sum to 'num'. Note: Given array/list can contain duplicate elements ...

Abstract: As is well known, the prototype coprime arrays consist of two collinear subarrays, whose physical sensor number is coprime to each other. Moreover, their larger inter-element separations and ...

You are given a positive integer array nums. The element sum is the sum of all the elements in nums. The digit sum is the sum of all the digits (not necessarily distinct) that appear in nums. Return ...

ABSTRACT: Let G be a finite nilpotent group of odd order and S be a subset of G\{0}. We say that S is complete if every element of G can be represented as a sum of different elements of S and ...
