Functions

func Reverse

func Reverse(s string) string

Reverse gives the reversed form of s.

This implementation improves performance by removing unnecessary string conversions. Further improvements could be made by:

1. Preallocating enough capacity in out. 2. Remove out and sort the input in place. 3. Use a specially designed type like strings.Builder from the stdlib. 4. Something much more complicated.

As mentioned in example3 this fails on combining characters like "noël". For a correct version see: http://rosettacode.org/wiki/Reverse_a_string#Go
