Given an array ARR of N integers and an integer S. The task is to find whether there exists a subarray(positive length) of the given array such that the sum of elements of the subarray equals to S or not. If any subarray is found, return the start and end index (0 based index) of the subarray. Otherwise, consider both the START and END indexes as -1.

Note:

If two or more such subarrays exist, return any subarray.

For Example: If the given array is [1,2,3,4] and the value of S is equal to 7. Then there are two possible subarrays having sums equal to S are [1,2,3] and [3,4].

Asked in-depth about my project. I was also asked to show it using the screen share. Picked up lines and was asked to explain. Asked me to add another menu and show her (web development project). Difference between get and post methods. Why I code HTML, CSS, bootstrap, etc, and why not react. What would I study web development when I could easily build sites using WordPress etc. If there is a huge project and I had to fix an error, how do I find out in which file the error exists? If suppose your manager comes and tells you that you have made a mistake and that your code is not working properly, how would you handle it? What would you do if you were placed in a team, where the work is monotonous and there is nothing new to learn and you have been placed there since you made mistakes in other groups before.
