Interview Process
The interview consisted of two coding questions: one medium difficulty and one hard difficulty.
Technical Questions
- Medium Question: Given an array and an integer k, find the minimum length of a subarray that contains at least k different numbers.
- Hard Question: Given two arrays A and B, you can perform two types of operations: increment all numbers before a chosen index i in A by 1, or increment all numbers after index i in A by 1. Determine the minimum number of operations required to make A equal to B.
- Example: For A = [2, 3, 4] and B = [3, 3, 5], the operations would be:
- Operation 1: 2 + 1 = 3
- Operation 2: 4 + 1 = 5
- Total operations = 2.
- Example: For A = [2, 3, 4] and B = [3, 3, 5], the operations would be:
