yes bro actually i have discovered the testcase on which your code is going wrong is:- n=5,c=0 a={1,0,0,0,1}; the output for this should be 0 1 2 3 4 but your code is giving the output 0 1 2 4 4. please fix this error. if even after that you are facing the problem tell me the logic you have used,may i help you. i am attaching my submission,that i solved[submission:266644623] for the reference. hopefully it would work.
