Problem: Snuke has an integer sequence A of length N.  He will freely choose an integer b. Here, he will get sad if A_i and b+i are far from each other. More specifically, the _sadness_ of Snuke is calculated as follows:    * abs(A_1 - (b+1)) + abs(A_2 - (b+2)) + ... + abs(A_N - (b+N))  Here, abs(x) is a function that returns the absolute value of x.  Find the minimum possible sadness of Snuke.

Problem: Snuke has an integer sequence A of length N.  He will freely choose an integer b. Here, he will get sad if A_i and b+i are far from each other. More specifically, the _sadness_ of Snuke is calculated as follows:    * abs(A_1 - (b+1)) + abs(A_2 - (b+2)) + ... + abs(A_N - (b+N))  Here, abs(x) is a function that returns the absolute value of x.  Find the minimum possible sadness of Snuke.

Problem: Snuke has an integer sequence A of length N.  He will freely choose an integer b. Here, he will get sad if A_i and b+i are far from each other. More specifically, the _sadness_ of Snuke is calculated as follows:    * abs(A_1 - (b+1)) + abs(A_2 - (b+2)) + ... + abs(A_N - (b+N))  Here, abs(x) is a function that returns the absolute value of x.  Find the minimum possible sadness of Snuke.
