Least Machine Problem

Problem Statement

You are given start time and end time for a task. They are provided in slices in this format:

start = []int{task1startTime, task2startTime, task3startTime, ...}
end = []int{task1endTime, task2endTime, task3endTime, ...}

There can be several machines which perform these tasks. Each machine can only do one task at a time.
Efficiently allocate tasks to the machines so that least numbers of machines are required to perform all the tasks.

Constraints

• Length of both slices will always be equal.
• start[i] will always be less than end[i].

Example

start = []int{2, 1, 5, 5, 8}
end = []int{5, 3, 8, 6, 12}

Machine 1 = [(2, 5), (8, 12)]
Machine 2 = [(1, 3), (5, 8)]
Machine 3 = [(5, 6)]

So, the least number of machines required, count(Machine) is 3.

Solution

func GetLeastRequiredMachine(start, end []int32) int32

Function GetLeastRequiredMachine solves the given problem by finding the available machine after each iteration, giving the result we're expecting.

Execution

Run the tests already provided.
