**Round 2: Coding (2 Questions – 75 Minutes)**

**Question 1: **

You were playing a game of treasures where the treasure boxes were kept in a row. Each treasure box has a label denotes the amount placed inside the treasure box. A lock is designed to lock multiple treasure boxes next to each other in a row. Each treasure box is locked with zero or more number of such locks.

Your task is to unlock only one lock where you could get the maximum treasure amount from the boxes. There could be treasure boxes without any locks as well. On finding the maximum treasure amount, you should consider the boxes without the locks as well.

**Input Format: **

The first line contains a single integer N, the number of treasure boxes.

The next line contains N space separated integers A[i], the amount in ith box.

The next line contains a single integer K, the number of locks.

The next K line contains two space separated integers S[i] and E[i], the start and end of ith lock in the row.

** Output Format:**

Print the maximum amount M., can be found on unlocking only one lock.

**Constraints:**

1 <= N, K <= 100

0 <= A[i] <=10^6

1 <= S[i] <= E[i] <= N

** Explanation:**

There are N = 5 treasure boxes with amounts A = [2, 5, 6, 1, 4] and K= 3 locks.

Lock1 is used to lock boxes starts from 2nd position to 3rd position.

Lock2 is used to lock boxes starts from 3rd position to 4th position.

Lock3 is used to lock boxes starts from 3rd position to 5th position.

So when the lock1 is unlocked. you can find maximum amount 7 (2 + 5).

**Sample Input:**

Next line consists of K space-separated integers w[i], weight of ith good.

Next line consists of a single integer W, vehicle capacity of weights.

**Output Format:**

Print the number of ways to fill the vehicle for the given capacity of weights.

**Constraints:**

1 <= K <=20

1 <= w[i] <= 100

1 <= W <= 1000

**Explanation:**

There are 4 ways to fill the vehicle with weight = 4. using weights of goods w = [1, 2, 3].

{1, 1, 1, 1}

{1, 1, 2}

{1, 3}

{2, 2}

**Sample Input:**
