TikTok Software Engineer Internship interview questions

They ask complex string manipulation questions

1. Given an array nums which consists of only '0's and '1's where '1' denotes there's a stone at a given position, an index p, and an integer k. Find the minimum steps needed to stack at least k stones at position p. Within one step, you're only allowed to move one stone to an adjacent position. # nums: [1,0,1,0,0,1] # k: 2 # p: 2 # result=2 Followup：# Given an array nums which consists of only '0's and '1's where '1' denotes there's a stone at given position, and an integer k.
