Understanding the Shortest Distance After Road Addition Queries I I Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
You are given an integer n and a 2D integer array queries. There are n cities numbered from 0 to n - 1. Initially, there is a unidirectional road from city i to city i + 1 for all 0 <= i < n - 1. queries[i] = [ui, vi] represents the addition of a new unidirectional road from city ui to city vi. After each query, you need to find the length of the shortest path from city 0 to city n - 1. There are no two queries such that queries[i][0] < queries[j][0] < queries[i][1] < queries[j][1]. Return an array answer where for each i in the range [0, queries.length - 1], answer[i] is the length of the shortest path from city 0 to city n - 1 after processing the first i + 1 queries.

Get real-time assistance for Shortest Distance After Road Addition Queries II problems during coding interviews. Interview Coder provides instant solutions and explanations.
Examples
n = 5, queries = [[2,4],[0,2],[0,4]][3,2,1]After the addition of the road from 2 to 4, the length of the shortest path from 0 to 4 is 3. After the addition of the road from 0 to 2, the length of the shortest path from 0 to 4 is 2. After the addition of the road from 0 to 4, the length of the shortest path from 0 to 4 is 1.
n = 4, queries = [[0,3],[0,2]][1,1]After the addition of the road from 0 to 3, the length of the shortest path from 0 to 3 is 1. After the addition of the road from 0 to 2, the length of the shortest path remains 1.
Constraints
3 <= n <= 1051 <= queries.length <= 105queries[i].length == 20 <= queries[i][0] < queries[i][1] < n1 < queries[i][1] - queries[i][0]There are no repeated roads among the queries.There are no two queries such that i != j and queries[i][0] < queries[j][0] < queries[i][1] < queries[j][1].How Interview Coder Helps with Leetcode Problems
