Reverse an ASCII string
Your goal is to reverse an ascii string. Given a (optionally newline or null terminated) input, output your input in reverse order, optionally followed by a newline. Terminate afterward. Function answers will not be given a newline, and are not expected to output one unless they print the answer to console.
Examples
Assume all inputs are followed by a newline, and are all standard ASCII encoded.
abcdef -> fedcba
Hello, World! -> !dlroW ,olleH
racecar -> racecar
Example program
function solution(x) {
return x.split("").reverse().join("");
}
Further clarifications
- No, you don't have to handle nulls correctly.
- Nor empty inputs.
