function UnionFind(n) {
    this.s = []; // Underlying array
    this.numSets = n;
    for (var i = 0; i < n; i++) // initial representatives are -1

## xclip aliases for startup scripts
# to simplify life, install xclip and append the following lines to your .bashrc
alias "c=xclip" # copy to X clipboard (register *)
alias "cs=xclip -selection clipboard" # copy to system wide clipboard (register +)
alias "v=xclip -o" # output copied content (paste)
alias "vs=xclip -o -selection clipboard" # paste from system wide clipboard (equivalent to `v -selection clipboard`)

# examples:
# copy to X:
# go to the same directory in terminal 2 as in terminal 1
# Terminal 1:
