Find a triplet that sum to a given value in C++
In this tutorial, we are going to write a program that finds the triplet in the array whose sum is equal to the given number.
Let's see the steps to solve the problem.
Create the array with dummy data.
Write three inner loops for three elements which iterate until the end of the array.
Add the three elements.
Compare the sum with the given number.
If both are equal, then print the elements and break the loops.
Example
Let's see the code.
#include <bits/stdc++.h>
using namespace std;
bool findTriplet(int arr[], int arr_size, int sum) {
for (int i = 0; i < arr_size - 2; i++) {
for (int j = i + 1; j < arr_size - 1; j++) {
for (int k = j + 1; k < arr_size; k++) {
if (arr[i] + arr[j] + arr[k] == sum) {
cout << arr[i] << " " << arr[j] << " " << arr[k] << endl;
return true;
}
}
}
}
return false;
}
int main() {
int arr[] = { 1, 2, 3, 4, 5, 6, 7 };
findTriplet(arr, 7, 12);
return 0;
}Output
If you execute the above program, then you will get the following result.
1 4 7
