Confusion in question

#1

Here stalls are located in random manner so is it necesseary to sort the stalls …beacuse without sorting i am getting 4 as the largest minimum separation…which is true also for 1 2 8 4 9 …having 3 cows…
But this approch i am not passing any testcases…
When i sort the array and then calculate the minimum distance it passed all test cases.

#2

You have to sort the array in order to apply binary search

#3

But we are not applying the binary search on this array… The “sta” and “end” which we have created …we are applying binary search on that… didn’t we??

#4

You should apply binary search on the minimum distance between any two cows.
