<new line>ab<backspace>si<carriage return>ha
First, handle the backspace. Note that even though it is "non-erase", the next character to be output would overwrite what was backspaced over:
<new line>asi<carriage return>ha
Now, a carriage return means to go back to the beginning of the line. So the "ha" overwrites the "as" in "asi:
<new line>hai
Now, the cursor is currently sitting on the i, so the next character to be output would overwrite i.

In a gymnastic competition, scoring is based on the average of all scores given by the judges excluding the maximum and minimum scores. Let the user input the number of judges, after that, input the scores from the judges. Output the average score. Note: In case, more than two judges give the same score and it happens that score is the maximum or minimum then just eliminate two scores. For example, if the number of judges is 5 and all of them give 10 points each. Then the maximum and minimum score is 10. So the computation would be 10+10+10, this time. The output should be 10 because 30/3 is 10.
