Comments on Reverse an ASCII string

Reverse an ASCII string

+11
−0

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.

Why does this reverse the input string?

Input is pushed to the stack one character at a time. When it's printed the last character is the top of the stack, so it's popped and printed first.
