//Find two smallest integers

using namespace std;

// implement printArray here

// implement findTwoSmallest here

// DO NOT WRITE ANY CODE BELOW THIS LINE (EXCEPT FOR TESTING - REMOVE BEFORE SUBMITTING)
int main() {

//Sample return
Enter number of integers: 5
Enter 5 integers: 92 10 23 17 10
Array contents: 92 10 23 17 10
Smallest: 10
Second smallest: 17

#include <iostream>
#include <string>

using namespace std;

// implement printArray here
void printArray(int arr[], int size) {
    for (int i = 0; i < size; ++i) {
        cout << arr[i] << " ";
    }
    cout << endl;
}

// implement findTwoSmallest here
void findTwoSmallest(int arr[], int size) {
    int min1 = arr[0], min2 = arr[1];
    if (min1 > min2) {
        int temp = min1;
        min1 = min2;
        min2 = temp;
    }
    for (int i = 2; i < size; ++i) {
        if (arr[i] < min1) {
            min2 = min1;
            min1 = arr[i];
        } else if (arr[i] < min2 && arr[i] != min1) {
            min2 = arr[i];
        }
    }
    cout << "Smallest: " << min1 << endl;
    cout << "Second smallest: " << min2 << endl;
}
