Help!!

Hey @Bhawna
Your code is working without any compilation error on my side,please elaborate your doubt :slight_smile:

#3

Getting wrong answer using same code

#4

Hey @Bhawna
Updated this https://ide.codingblocks.com/s/357290
But this will only work when nums are between 0-9 but this is not the case here,so u have to take strings instead and solve it using strings instead of char array

Or
convert ever digit of the number to char and then insert it into char array
for -54 insert - then 5 then 4
its much complex in char array

#5

pre[i]=root->val+‘0’; //Updated this

     pre[i++]='L'; //added this

     preorder(root->left,pre,i);

     pre[i++]='R';//added this

     preorder(root->right,pre,i);

I didn’t understand above clearly

#6

This is converting an integer digit to char digit

Whenever we go left sub node we add L to our array

Similarly for R

otherwise say

      1
          2  
              3
this and 
       1
    2
        3
will have same array
