Document Summary

P = 1, difference = |3 10| = 7. P = 4, difference = |10 3| = 7. Write a function: function solution(a); that, given a non-empty array a of n integers, returns the minimal difference that can be achieved. function solution(a) { var first = a[0]; var s0 = function(a){ return a. reduce(function(a1,b1){ return a1 + b1. // write your code in javascript (node. js 8. 9. 4) **a non-empty array a consisting of n integers is given. A permutation is a sequence containing each element from 1 to n once, and only once. A[0] = 4 a[1] = 1 a[2] = 3 a[3] = 2 is a permutation, but array a such that: A[0] = 4 a[1] = 1 a[2] = 3 is not a permutation, because value 2 is missing. The goal is to check whether array a is a permutation.
