**Largest Pair of Points - Google Top Interview Questions**

### Problem Statement :

You are given a strictly increasing list of integers nums and a list of integers values, both of the same length. Find a pair i ≤ j that maximizes values[i] + values[j] + nums[j] - nums[i] and return the value. Constraints 2 ≤ n ≤ 100,000 where n is the length of nums and values Example 1 Input nums = [0, 1, 6] values = [-5, 5, 4] Output 14 Explanation Here we can pick i = 1 and j = 2 to get 5 + 4 + 6 - 1 Example 2 Input nums = [0, 3, 6] values = [-5, 4, 8] Output 16 Explanation Here we can pick i = 2 and j = 2 to get 8 + 8 + 6 - 6

### Solution :

` ````
Solution in C++ :
int solve(vector<int>& nums, vector<int>& values) {
int jsum = INT_MIN, isum = INT_MIN;
for (int i = 0; i < nums.size(); i++) {
int sum = nums[i] + values[i];
jsum = max(jsum, sum);
sum = values[i] - nums[i];
isum = max(isum, sum);
}
return isum + jsum;
}
```

` ````
Solution in Java :
import java.util.*;
class Solution {
public int solve(int[] nums, int[] values) {
int N = nums.length;
int max = Integer.MIN_VALUE;
int ans = Integer.MIN_VALUE;
for (int j = 0; j < N; j++) {
max = Math.max(max, values[j] - nums[j]);
ans = Math.max(ans, nums[j] + values[j] + max);
}
return ans;
}
}
```

` ````
Solution in Python :
class Solution:
def solve(self, nums, values):
ans = -1e18
best = -1e18
for num, value in zip(nums, values):
best = max(best, value - num)
ans = max(ans, num + value + best)
return ans

## Queue using Two Stacks

A queue is an abstract data type that maintains the order in which elements were added to it, allowing the oldest elements to be removed from the front and new elements to be added to the rear. This is called a First-In-First-Out (FIFO) data structure because the first element added to the queue (i.e., the one that has been waiting the longest) is always the first one to be removed. A basic que
