String Combine problem

[Richard Zenn]

Hello,

I have a algorithm problem and I'm trying to resolve it

Here is an array s = ["aaa", "b", "c", "d", "ee", "f"]
I want to combine them with some rules

1.
s.size > s[i+1].size
combine them
2.
s[i+1].size > s.size
combine them
3.
s.size + s[i+1].size

The upper result is

{"aaab"}
{"bc"}
{"bcd"}
{"cd"}
{"dee"}
{"eef"}

Thanks for any help

Richard

Wow!it helps a lot

"b", "c", "d" is "one" character
they combine in order

array s = ["aaa", "b", "c", "d", "ee", "f"]

the rule 3 result will be "bc" "cd" "bcd"

Thanks for your help

In the first place, it seems that rules 1 and 2 combine to just say that
they should not be equal in size.

In the second place, if I read the rules correctly, they say that the
result you want is not correct.

Note: I am assuming that rule 3 is not a rule as much as it is an
example of how they should be combined.

s = ["aaa", "b", "c", "d", "ee", "f"]
arr = Array.new
0.upto(s.length - 2) { |i|
arr << s + s[i+1] unless s.size == s[i+1].size
}
p arr

=> ["aaab", "dee", "eef"]

"b", "c", "d" are all the same size and would be excluded by the rules.
Could you clarify? I must be missing something.
