rindex(p1) public

Returns the index of the last object in self

to obj. If a block is given instead of an

argument, returns first object for which block is true, starting from the last object. Returns nil if no match is found. See also Array#index.

If neither block nor argument is given, an enumerator is returned instead.

a = [ "a", "b", "b", "b", "c" ]
a.rindex("b")        #=> 3
a.rindex("z")        #=> nil
a.rindex{|x|x=="b"}  #=> 3
