Minimum Time To Solve The Problems

Given 'N' subjects, each containing a certain number of problems, and 'K' friends, assign subjects to friends such that each subject goes to exactly one friend, maintaining contiguity in assignment, aiming to minimize the maximum number of problems any single friend receives. Each problem takes 1 unit of time to solve. Determine the minimum possible time required for the most loaded friend.

Example:

Input:

 N = 4
K = 2
subjects = {50, 100, 300, 400}

Output:

400

Explanation:

The optimal assignment of subjects is {50, 100, 300} for the first friend and {400} for the second friend. The maximum time any friend takes in this setup is 400, which is minimal.

Constraints:

• 1 <= T <= 10
• 1 <= N, K <= 10^4
• 1 <= subjects[i] <= 10^9
• Time limit: 1 second
