u are trying to access -1 index when the array is already sorted

so basically garbage value at arr[i-1] is being swapped with arr[index]

so isliye u are getting a wrong answer in hackerblock

where in vs code , there is some way by which code is getting correct o/p

in all, u need to handle the case when array is already sorted

#6
#7

But if the array is sorted the swap never happens . So the negative index should not come into picture.

#8

u have not put any condition if the array is already sorted ( in decreasing order)

as i have shown with the highlighted part
in case the array is in decreasing order then i = 0 and then u swap ( a[i-1], a[idx])

alright got it ! thank you so much
