First round:

OA using hackrank

Has 2 question with total 120 marks and required 60 marks to pass.

First question: 70 marks for this question Tasks with memory required to process are given which should be run in a processor. Tasks : [1,4,5,2,3] (the numbers represent memory needed) Type of tasks are given in another array Task Type : [1,2,1,3,4] Another input is given which is the max memory the processor can run at a time. Max_memory : 6 Now only two tasks with same task type can run in parallel. Assume each tasks take 1 unit of time. Find out the time taken to complete all the tasks. Sample output : 4 units. Because there are two tasks of type 1 and adding their memory is 6 which is eq to max_memory. So they ll run in parallel. All other tasks are of different types and their memories are less than max_memory. So they ll each take 1 unit of time.

Second question: 50 Marks, tell which zone this ip address is condition is given for each zone.
