λ pcs cargo run p 202 Finished dev [unoptimized + debuginfo] target(s) in 0.13s Running `target/debug/leetcode p 202` [202] Happy Number is on the run... Write an algorithm to determine if a number is "happy". A happy number is a number defined by the following process: Starting with any positive integer, replace the number by the sum of the squares of its digits, and repeat the process until the number equals 1 (where it will stay), or it loops endlessly in a cycle which does not include 1. Those numbers for which this process ends in 1 are happy numbers. -------------------------------------------------- Example: Input: 19 Output: true Explanation: 12 +たす 92 =わ 82 82 +たす 22 =わ 68 62 +たす 82 =わ 100 12 +たす 02 +たす 02 =わ 1

We can write like:
pub fn superscript(n: u8) -> String { match n { 0 => "0".to_string(), 1 => "1".to_string(), 2 => "2".to_string(), 3 => "3".to_string(), 4 => "4".to_string(), 5 => "5".to_string(), 6 => "6".to_string(), 7 => "7".to_string(), 8 => "8".to_string(), 9 => "9".to_string(), x if x > 10 => (superscript(n / 10).parse().unwrap_or(0) + &superscript(n % 10).parse().unwrap_or(0)) .to_string(), _ => n.to_string(), } } }
