What will be the output of the following code?
#include <bits/stdc++.h>
using namespace std;
void func(int a[], int n, int k)
{
if (k <= n)
{
for (int i = 0; i < k/2; i++)
swap(a[i], a[k-i-1]);
}
}
int main()
{
int a[] = {1, 2, 3, 4, 5};
int n = sizeof(a) / sizeof(int), k = 3;
func(a, n, k);
for (int i = 0; i < n; ++i)
cout << a[i]<<" ";
return 0;
}
#include <bits/stdc++.h>
