i++ and ++i mean the same thing but they have differently
i++ define post increment that means when the function
is completely after that the value is increment
Example:
i=4 find d=i++ + i; d=9 because i++
initially the value is 4 so 4+4=8 after tha the value d is
increment so finally d value is 9
++i define pre increment that means when the function
is starting increment
Example:
i=4 find d=++i +i; d=9 ++i value is increment
starting so ++i value is 5 so d value is 9

given post order,in order construct the corresponding binary tree
