The last two outputs have order of "a" and "b" reversed - that can
never be the result of simply inserting something into "ab". Are
those typos or is it intentional? If it is intentional, what is it
that you _really_ want?
In case of type, please have a look:
irb(main):001:0> st = 'ab'
=> "ab"
irb(main):002:0> ch = 'c'
=> "c"
irb(main):003:0> 3.times {|i| puts st.dup.insert(i, ch)}
cab
acb
abc
=> 3
Kind regards
