What will happen when instead of return bubble2sort() when j==n-1 we simply called bubble2sort() without return statement

#1

recursive call with return statement works in different way? please explain how

#2

hello @the.shubham.sri
if we not use return in that if statement ,then whatever statement written after that if,will execute and error will occur.
becuase u will try to access j and j+1 ,where j =n-1 and j+1=n,we cannot acces index n in our array(because array size is n ,index range from 0 to n-1) this will give error
