Good Subarrays

Given an array of integers A. A subarray of an array is said to be good if it fulfills any one of the criteria: 1. Length of the subarray must be even and the sum of all the elements of the subarray must be less than B. 2. Length of the subarray must be odd and the sum of all the elements of the subarray must be greater than B. Your task is to find the count of good subarrays in A. If the count of good subarrays exceeds 10^9 then return 10^9. Input Format

How to write better code?

The example has been picked from operationsdashboard/src/Demo/Flight/Preflightdata.js

In order to write better code, we should always think about readiblity of code and nameing conventions. Readibility of code make it easy for new developer to adopt the code and make new changes. For example you can see t5, t4, convertTime2, etc in the code. Any new developer can not understant the code directly, he/she must have to read the entire code and understand it's uses.

Old code
