Solve Time-Window and Binary Swap Problems

Q: Solve Time-Window and Binary Swap Problems

This assessment evaluates algorithmic proficiency in time-based counting and synchronous string transformation, covering competencies in windowed aggregation, array and binary-string processing, simulation of concurrent swaps, and algorithmic complexity analysis.

Q: How do I approach Coding & Algorithms interview questions?

Coding & Algorithms questions require understanding of core concepts and practice. PracHub provides solutions with explanations to help you master coding & algorithms interviews.

Question

This online assessment contained two coding problems:

Maximum requests in a time window
You are given a non-decreasing integer array requestTimes , where requestTimes[i] is the second at which the i -th request arrives, and an integer windowSize . Return the maximum number of requests that occur within any inclusive time interval of length windowSize seconds. In other words, find the largest number of elements that can fit inside some interval [t, t + windowSize] .
Simultaneous swaps in a binary string
You are given a binary string s consisting only of '0' and '1' . Every second, all adjacent occurrences of '01' are swapped simultaneously to become '10' . Repeat this process until the string no longer contains '01' . Return the number of seconds required.

Example: s = "001011" transforms as follows: 001011 -> 010101 -> 101010 -> 110100 -> 111000 So the answer is 4 seconds.
