Can anyone help me with this code?

The findElement function was supposed to return 4 but it's returning -1. https://code.sololearn.com/cbzZQA8QZXIu/?ref=app

For binary search, the elements must be in sorted order..!

I watched a YouTube explanation of this problem and it says this uses binarysearch cuz a part of the array is sorted so it does binary search on that part!Jayakrishna🇼🇳

Ok. index 4<4 is stoping loop so < instead of <= in while(start <= end) solve issue. but it may be only for this case.

//while (start < end) { while (start <= end) { I checked only this array example but it can search all elements
