Bubble sort recursion

#1

in the function definition we used data type void but in the base case we use return bubble_sort(a,0,n-1)
how can we return something if we use data type void.

#2

hello @jindaldivish
return bubble_sort(a,0,n-1) statement will first call bubble_sort function and return the value that this called function will give.
and because bubble sort is of void type it will give nothing.
and hence return statement will return nothing (i.e void) only control will get transferred to the calling function.
