LeetCode ProblemMaximum Segment Sum After Removals
You are given two 0-indexed integer arrays nums and removeQueries, both of length n. For the ith query, the element in nums at the index removeQueries[i] is removed, splitting nums into different segments. A segment is a contiguous sequence of positive integers in nums. A segment sum is the sum of every element in a segment. Return an integer array answer, of length n, where answer[i] is the maximum segment sum after applying the ith removal. Note: The same index will not be removed more than once.

Problem Breakdown
Understanding the Maximum Segment Sum After Removals Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
You are given two 0-indexed integer arrays nums and removeQueries, both of length n. For the ith query, the element in nums at the index removeQueries[i] is removed, splitting nums into different segments. A segment is a contiguous sequence of positive integers in nums. A segment sum is the sum of every element in a segment. Return an integer array answer, of length n, where answer[i] is the maximum segment sum after applying the ith removal. Note: The same index will not be removed more than once.

How Phantom Code Helps
Get real-time assistance for Maximum Segment Sum After Removals problems during coding interviews. Phantom Code provides instant solutions and explanations.
Examples
# Example 1
Input
nums = [1,2,5,6,1], removeQueries = [0,3,2,4,1]
Output
[14,7,2,2,0]
# Example 2
Input
nums = [3,2,11,1], removeQueries = [3,2,1,0]
Output
[16,5,3,0]
Constraints
n == nums.length == removeQueries.length
1 <= n <= 105
1 <= nums[i] <= 109
0 <= removeQueries[i] < n
All the values of removeQueries are unique.
