Solve code for C++: 

#include  using namespace std; //You need to implement two functions below. //Function 1: 25 points bool exists_trio(int*,int); //Input: //an integer array (param 1) and its size (param 2) //Output: //True or false //Behavior: //Returns true is there exists //a sequence of 3 *consecutive* values in the array //such that the sum of the first two elements //is equal to the third element in that //sequence, false otherwise. //Example: //For the array {3,4,1,3,17,3,20,21,5,96}, //the function returns true because of the // sequence {17,3,20} (i.e., 17+3=20). //For the array {3,4,1,3,3,7}, //the function returns false. //Function 2: 25 points bool exists_trio_within_distance(int*,int,int); //Input: //an integer array (param 1), its size (param 2), and //a distance (param 3) //Output: //True or false //Behavior: //Returns true is there exists //a sequence of 3 values in the array //such that sum of the first two elements //is equal to the third element in the //sequence. The third element has to be //within a distance of dist from the //second element. //False otherwise. //Example: //For the array {3,4,1,3,17,3,96,21,5,20}, //if dist is 7 //the function returns true because // 4+1=5 and the element 5 is within 7 spots //from element 1. //For the array {3,4,1,3,3,7}, //if dist is 2, //the function returns false. //This is because, even though 3+4=7, //element 7 is not within a distance of 2 //from element 4. int main() { int asize=10; int a[asize]={3,4,1,3,17,3,20,21,5,20}; int bsize=6; int b[bsize]={3,4,1,3,3,7}; ////////////////////////////////////////// //test exists_trio function //should print "A trio exists." if (exists_trio(a,asize)) cout << "A trio exists.
