#### First element in sorted array greater than target

Given a sorted array and a target value, this problem asks to find the index of the first element in the array that is greater than the target. For example, given the array [1 , 2, 3, 4, 5] and target value 3, the output would be 2 since 2 is the index of the first element in the array (4) that is greater than the target value.

#### Problem

```Find the index of the first element in a sorted array that is greater than a given target value.
Input: [1, 2, 3, 4, 5], target = 3
Output: 2```

#### Solution

This solution is in C++. Our A.I. can create solutions in multiple languages.
```#include <iostream>
#include <vector>

using namespace std;

int find_first_greater_than(vector<int>& arr, int target) {
int left = 0;
int right = arr.size() - 1;
int mid;
while (left <= right) {
mid = left + (right - left) / 2;
if (arr[mid] > target) {
right = mid - 1;
} else {
left = mid + 1;
}
}
return left;
}

int main() {
vector<int> arr = {1, 2, 3, 4, 5};
int target = 3;
cout << find_first_greater_than(arr, target) << endl;
return 0;
}```
