hello Akshat,
u are handling case when child=1 in ur build function

#3

let alone case when child==1, for child =2 and 0 it should work. Given input is having child=0 or 2 only.

#4

@akshatkaush
sorry didnt get what u r saying

no of child can be 1 as well. in question it is mentioned that no of child will not exceed 2

#5


please check it now…

#6

now it is almost correct.
i have made some changes pls check->

#7

thank you for the solution but can you explain why you added NULL at the end of the function

#8

@akshatkaush
that return statement will never execute.

i put it there because without that statement compiler will think that we are not returning anything and will raise compile error
