C++ Programming Problem: Newton is a brilliant mathematician and solving triangles problems fascinates him. Today he is given a sequence of positive integers V1, V2, ., VN. You must choose three elements Vx, Vy, Vz (x, y, z is vertices) such that the triangle formed have these properties: |XY|= Vz, |XZ|=Vy, |YZ|=Vx and the angle |ZYXZ|= 0 satisfies cose2P/Q, where 0 should be maximum possible. Find any such triangle or determine that it does not exist. Develop a C++ code which prints the value of x, y, z in a single line and print "Invalid" if not possible. Test Case: 412 9765 Result: 324

Please Help In JAVA Here is the skeleton of a code for insertion sorting in an imperative language. You have to add right lines of codes for the language you choose (C, C++, C#, JAVA etc,). The following sample is for C++. #include <iostream>#include <array>#include <stdio.h>#include <stdlib.h>#include <ctime>using namespace std; void insertionSort(int A[], int n){for (int i = n-2; i >= 0; i--){ int j; int v = A[i]; for (j = i + 1; j <= n-1; j++) { if (A[j] > v) break; else A[j-1] = A[j]; } A[j-1] = v;}} int *randomArray(int n){srand((unsigned) time(0));int * A = new int [n];for (int i = 0; i < n; i++){ A[i] = rand();}return A;} Sample function calls (call these functions in main driver function):int n = 100000;int * A = randomArray(n);insertionSort(A, n);delete [] A; Note: delete memory of first array before sorting second array. After you modify the code: (1) Generate 100, 000 random numbers and sort them (2) Generate 300000…
