Topological Sort

Topological sort is a sorting technique that sets up a hierarchy in a process. In this technique, when a directed network has nodes connected by arrows, the root node is placed before the successor node.

There are N balls positioned in a row. Each of them is either red or white. In one
move we can swap two adjacent balls. We want to arrange all the red balls into a
consistent segment. What is the minimum number of swaps needed?
Write a function:
class Solution {public int solution (String S); }
that, given string S of length N built from characters "R" and "W", representing
red and white balls respectively, returns the minimum number of swaps needed
to arrange all the red balls into a consistent segment. If the result exceeds 10⁹,
return -1.
Examples:
1. Given S="WRRWWR", your function should return 2. We can move the last ball
two positions to the left:
"WRRWRW"
• "WRRRWW"
