Hi if i want to count the number of times values are repeated in an
array how do i go about it...is there a method?
My solution is
list.sort
loop through list and compare one element to the next and count
repetitions.
is there a simpler way?
Also
in C i used the for loop a lot to loop through arrays but i notice that
in ruby using
list.each do |element|
..
..
end
is quite popular.
If i wanted to do someting like this:
if list[currElement] == list[currElement + 1]
...
How would i go about writing that using list.each do |element|?
Any help greatly appreciated.
