Strings and Runes

The problem to be solved in this challenge is to understand how to work with strings and runes in Go. Specifically, the challenge will cover how to get the length of a string, how to index into a string, how to count the number of runes in a string, and how to iterate over the runes in a string.

Requirements

To complete this challenge, you will need:

• A basic understanding of Go syntax
• Knowledge of Go strings and runes
• The Go standard library

Example

$ go run strings-and-runes.go
Len: 18
e0 b8 aa e0 b8 a7 e0 b8 b1 e0 b8 aa e0 b8 94 e0 b8 b5
Rune count: 6
U+0E2A 'ส' starts at 0
U+0E27 'ว' starts at 3
U+0E31 'ั' starts at 6
U+0E2A 'ส' starts at 9
U+0E14 'ด' starts at 12
U+0E35 'ี' starts at 15

Using DecodeRuneInString
U+0E2A 'ส' starts at 0
found so sua
U+0E27 'ว' starts at 3
U+0E31 'ั' starts at 6
U+0E2A 'ส' starts at 9
found so sua
U+0E14 'ด' starts at 12
U+0E35 'ี' starts at 15

Summary

This challenge covered how to work with Go strings and runes. It demonstrated how to get the length of a string, how to index into a string, how to count the number of runes in a string, and how to iterate over the runes in a string. By completing this challenge, you should have a better understanding of how to work with strings and runes in Go.
