P2127 Sorting a Sequence
Description
Xiao C has an integer sequence of $N$ numbers, in which all numbers are pairwise distinct.
Each time, Xiao C can swap any two numbers in the sequence, with a cost equal to the sum of those two numbers.
Xiao C wants to sort the entire sequence in ascending order. What is the minimal cost needed?
Input Format
The first line contains an integer $N$.
The second line contains $N$ integers, representing Xiao C's sequence.
Output Format
Output one line containing an integer, the minimal cost Xiao C needs.
Explanation/Hint
- For $30\%$ of the testdata, $N\le10$.
- For $100\%$ of the testdata, $1\le N\le10^5$, and the $N$ integers on the second line are positive integers not exceeding $10^9$.
