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.\n";
else
cout << "A trio does not exist.\n";
//should print "A trio does not exist."
if (exists_trio(b,bsize))
cout << "A trio exists.\n";
else
cout << "A trio does not exist.\n";
cout << "\n";

//test exists_trio_within_distance function
//if you only want to test exists_trio, comment
//out the below code
//change the array a to help test Function 2
a[6]=209; //change a[6] from 20 to 209
int dist=7;
//should print "A trio exists within distance 7."
if (exists_trio_within_distance(a,asize,dist))
cout << "A trio exists within distance " << dist << "." << endl;
else
cout << "A trio does not exist within distance " << dist << "." << endl;
dist=2;
//should print "A trio does not exist within distance 2."
if (exists_trio_within_distance(b,bsize,dist))
cout << "A trio exists within distance " << dist << "." << endl;
else
cout << "A trio does not exist within distance " << dist << "." << endl;
}
