Code Question 1: Server Channel Quality

Amazon's AWS provides fast and efficient server solutions. The developers want to stress-test the quality of the servers' channels. The following conditions must be met:

1. Each packet must be sent via a single channel.
2. Each channel must transfer at least one packet.

The quality of a transfer for a channel is defined by the median of the sizes of all data packets sent through that channel.

• Note: The median of an array is:
  • The middle element if the array is sorted in non-decreasing order.
  • If the number of elements is even, the median is the average of the two middle elements.

Task:
Find the maximum possible sum of the qualities of all channels. If the answer is a floating-point value, round it to the next higher integer.

---

Example:

Input:

• packets = [1, 2, 3, 4, 5]
• channels = 2

Steps:

1. At least one packet must be sent through each of the 2 channels.
2. A maximal solution is to transfer packets {1, 2, 3, 4} through channel 1 and {5} through channel 2.

Quality:

• Median of channel 1 = (2 + 3) / 2 = 2.5
• Median of channel 2 = 5

Sum = 2.5 + 5 = 7.5, rounded up to 8.

Output: 8

Function Description:

Complete the function findMaximumQuality in the editor below.

Parameters:

• int packets[n]: An array of packet sizes.
• int channels: The number of channels.

Returns:

• long int: The maximum sum possible.

Constraints:

• 1 <= len(packets) <= 5 × 10^5
• 1 <= packets[i] <= 10^9
• 1 <= channels <= len(packets)

Code Question 2: Lexicographical Array Generator

Your team is tasked with creating an array generator service to assist with software testing.

Input Parameters:

1. arr[n]: An array of n positive integers.
2. state: A binary string of length n where:
   • If state[i] = '1', then arr[i] is available.
   • If state[i] = '0', then arr[i] is blocked.
3. m: The number of operations to perform.

Task: To create an integer array S, perform the following operation exactly m times:

1. Choose any arr[i] that is available (state[i] = '1').
2. Append the value in arr[i] to S.
3. For all state[j] = '0' such that state[j-1] = '1', change state[j] to 1.

Return the lexicographically largest sequence S that can be obtained after m operations.

---

Example:

Input:

• arr = [10, 5, 7, 6]
• state = "1010"
• m = 2

Steps:

1. Start with state = "1010". Available elements: 10, 7.
2. Choose 10 → Append to S. Update state = "1110".
3. Choose 7 → Append to S.

Resulting S: [10, 7].

Output: [10, 7]

Function Description:

Complete the function generateNewArray in the editor below.

Parameters:

• int arr[n]: An array of integers.
• string state: A binary string indicating availability.
• int m: The number of operations.

Returns:

• int[m]: The lexicographically largest sequence S.

Constraints:

• 1 <= n, m <= 10^5
• 1 <= arr[i] <= 10^9
• |state| = n
• state[i] is either '0' or '1'.
• There is at least one '1' in state initially.
