Skuad Assignment - Parallel Log Proccessor API

Objective

• Design and Develop an API for analyzing log files parallelly.

• The solution should take a list of log files ("logFiles" -> array of strings) and count of parallel file processing ("parallelFileProcessingCount" -> integer) as input and output the number of exceptions grouped by time range and exception name. If processing for any file is finished then the next file should be picked immediately for processing, so that "parallelFileProcessingCount" number of files are being processed at every moment simultaneously, provided more than "parallelFileProcessingCount" number of files are remaining.
