Search Insert Position
Finds the index where a target value should be inserted in a sorted array using Binary Search.
#include <iostream>
#include <vector>
using namespace std;
int main() {
cout << "INSTRUCTIONS: Enter size n, n array elements, and then the target value." << endl;
int n, target;
cin >> n;
vector<int> a(n);
for (int i = 0; i < n; i++) cin >> a[i];
cin >> target;
int l = 0, r = n - 1;
while (l <= r) {
int mid = (l + r) / 2;
if (a[mid] == target) {
cout << mid;
return 0;
} else if (a[mid] < target)
l = mid + 1;
else
r = mid - 1;
}
cout << l;
