Given an array of size N in which every number is between 1
and N, determine if there are any duplicates in it. You are
allowed to destroy the array if you like.

Answer Posted / sankalan

sum all those no. say you get x
say there is a b (repeated) in place of a
so a-b = n(n+1)/2 - x=m(say)
sum the squares of those nos
say you get y
a^2-b^2 = 1/6(n+1)(2n+1)-y=n(say)
(a^-b^2)/(a-b)=a+b=m/n
to get a ((a+b)+(a-b))/2
to get b ((a+b)-(a-b))/2

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.
