Solution: Divide Chocolate

Explore how to apply a modified binary search approach to divide a chocolate bar into parts with maximum minimum sweetness. Learn to guess sweetness values and validate cuts effectively, optimizing divisions among friends in coding interviews.

Statement

You have a chocolate bar made up of several chunks, and each chunk has a certain sweetness, given in an array called sweetness. You want to share the chocolate with k friends. To do this, you’ll make k cuts to divide the bar into k + 1 parts. Each part will consist of consecutive chunks.

Being a kind person, you’ll take the piece with the minimum total sweetness and give the other pieces to your friends.

Your task is to find the maximum total sweetness of the piece you will receive if you cut the chocolate bar optimally.

Constraints:

  • 00 \leq k << sweetness.length 103\leq 10^{3}

  • 11 \leq sweetness[i] ...
