Document Summary

** an array a consisting of n integers is given. A triplet (p, q, r) is triangular if it is possible to build a triangle with sides of lengths a[p], a[q] and a[r]. In other words, triplet (p, q, r) is triangular if 0 p < q < r < n and: A[r] + a[p] > a[q]. function solution(a) { var a0 = a. length; var tricount =0; **a non-empty array a consisting of n numbers is given. The absolute distinct count of this array is the number of distinct absolute values among the elements of the array. The absolute distinct count of this array is 5, because there are 5 distinct absolute values among the elements of this array, namely 0, 1, 3, 5 and 6. Write a function: function solution(a) { var r = []; for(var i = 0; i < a. length; i++) if(!r. includes(math. abs(a[i]))){ r. push(math. abs(a[i])); return r. length; **let a be a non-empty array consisting of n integers.

16. The following method takes two integer arrays and a target integer as input. It is supposed to return true if there is an element from the first array and an element from the second array whose sum is the target integer. For instance, given arrays a=[1,4,3] and b=[2,6,3] and target 7, the method should return true because a[1]+b[2] = 4+3 = 7. However, if the target is 8, it should return false, as no element in array a, added with an element of array b results in 8. What should be the body of this method? public static boolean foo (int[] a, int[] b, int target) // What should go here? (A) for (int i = 0; i < a.length + b.length; i++) if(a[i] + b[i] == target) return true; else return false; (B) for (int i = 0; i

For any a < b, determine P(Y > a), and P(Y ∈ (a, b]). [3 marks]
