For N integers 0,1,,N1, a transformed sequence T can change i to Ti, where Ti{0,1,,N1} and i=0N1{Ti}={0,1,,N1}. x,y{0,1,,N1}, define the distance between x and y to be D(x,y)=min{|xy|,N|xy|}. Given the distance D(i,Ti) between each i and Ti, you must determine a transformed sequence T that satisfies the requirements. If many sequences satisfy the requirements, then output the lexicographically smallest one.

Note: For two transformed sequences S and T, if there exists a p<N that satisfies Si=Ti and Sp<Tp for i=0,1,,p1, then we say that S is lexicographically smaller than T.

Input Specification

The first line of input contains a single integer N, the length of the sequence. The following line contains N integers Di, where Di is the distance between i and Ti.

Output Specification

If there exists at least one transformed sequence T, then output one line containing N integers, representing the lexicographically smallest transformed sequence T. Otherwise, output No Answer.

Note: Pairs of adjacent numbers in the output must be separated by a single space, and there cannot be trailing spaces.
