string_permutation

Instructions

Define the function is_permutation that returns true if the string s1 is a permutation of s2, otherwise it returns false s1 is a permutation of s2 if all the elements in s1 appear the same number of times in s2 and all the characters in s1 appear in s2 even if in different order)

Expected Function

fn is_permutation(s1: &str, s2: &str) -> bool {
}

Usage

Here is a program to test your function.

fn main() {
	let word = "thought";
	let word1 = "thougth";
	println!(
		"Is `{}` a permutation of `{}`? = {}",
		word,
		word1,
		is_permutation(word, word1)
	);
}

And its output

student@ubuntu:~/[[ROOT]]/test$ cargo run
Is `thought` a permutation of `thougth`? = true
