Some hints: to get to the correct approach

  1. since a check on 1st pos is done if 1st pos has 9 it is not changed, u have to keep that case in mind
    think of how would u see wether this is the 1st positioned number when u are taking the no. from the right
    {hint: put a if condn (num/10 == 0) }

  2. reverse o/p is required, think of storing it in a vector, reversing the final output

  3. The conversion method is correct, just the o/p has to be reversed and the corner case of 9 in 1st position

#3

if i decalare a reverse function can it work or not.Can you code it?

#4

Yes, u can put the values in the vec and then use inbuild reverse function.
Please try to code it once, i can rectify the errors.
else u`ll not learn.
