MaxSliceSum A non-empty array A consisting of N integers is given. A pair of integers (P, Q), such that 0 ≤ P ≤ Q < N, is called a slice of array A. The sum of a slice (P, Q) is the total of A[P] + A[P+1] + ... + A[Q]. Write a function: class Solution { public int solution(int[] A); } that, given an array A consisting of N integers, returns the maximum sum of any slice of A. For example, given a..

EquiLeader A non-empty array A consisting of N integers is given. The leader of this array is the value that occurs in more than half of the elements of A. An equi leader is an index S such that 0 ≤ S < N − 1 and two sequences A[0], A[1], ..., A[S] and A[S + 1], A[S + 2], ..., A[N − 1] have leaders of the same value. For example, given array A such that: A[0] = 4 A[1] = 3 A[2] = 4 A[3] = 4 A[4] ..
