**First Fit Room - Amazon Top Interview Questions**

### Problem Statement :

You are given a list of integers rooms and an integer target. Return the first integer in rooms that's target or larger. If there is no solution, return -1. Constraints 0 ≤ n ≤ 100,000 where n is the length of rooms Example 1 Input rooms = [15, 10, 30, 50, 25] target = 20 Output 30 Explanation 30 is the first room that's at least as large as 20. Example 2 Input rooms = [15, 10, 30, 50, 25] target = 51 Output -1 Explanation There's no room that's at least 51.

### Solution :

` ````
Solution in C++ :
int solve(vector<int>& rooms, int target) {
auto it = find_if(rooms.begin(), rooms.end(), [&](int value) { return value >= target; });
return it == rooms.end() ? -1 : *it;
}
```

` ````
Solution in Java :
import java.util.*;
class Solution {
public int solve(int[] rooms, int target) {
for (int r : rooms) {
if (r >= target)
return r;
}
return -1;
}
}
```

` ````
Solution in Python :
class Solution:
def solve(self, rooms, target):
return next((x for x in rooms if x >= target), -1)
```

## Pair Sums

Given an array, we define its value to be the value obtained by following these instructions: Write down all pairs of numbers from this array. Compute the product of each pair. Find the sum of all the products. For example, for a given array, for a given array [7,2 ,-1 ,2 ] Note that ( 7 , 2 ) is listed twice, one for each occurrence of 2.
