Here the main function is calling itself so it is recursive calling and there is no breakdown condition so the program executes till stack overflow.

First s0 is printed then m1() will called which print s1 and executes loop two times and print s2 s3 s2 now when value of i becomes 1 it will break the loop without printing s3 and then print s4 of same function and then the control will return back to its calling place and executes next statements which is s5.
So the output of this program will be s0 s1 s2 s3 s2 s4 s5
