Errors In your code on https://ide.codingblocks.com/s/156275

  1. You have done j++ instead of ++j.
    ++j would first increment j and then return the value of j while j++ would first return the value of j and then increment it.
    Example j = 5
    j++ = returns 5 and increments j to 6
    ++j = increments j to 6 and then returns 6
  2. You have incremented j both in your first if statement and second if statement. While it should be only be incremented once for the left and right node, as they are on the same level.
  3. you have not defined the data type for it (iterator) in line 27
  4. Check my code on https://ide.codingblocks.com/s/156904 for necessary corrections
