Online Baliktarin ang String

How exactly can you take a string, split it, reverse it and join it back together again without the brackets, commas, etc. using python?

The question I am answering: Complete the solution so that it reverses the string value passed into it.

I answered this:

function solution(str){ str.split("").reverse().join(""); return(str);}

but it didnt work

Instead, this was the correct solution:

function solution(str){  return str.split("").reverse().join("");}

why is it that the second solution works but not the first?

If the string is "hello world", I need to flip every pair of characters and return "ehll oowlrd". The way I do it returns "olleh dlrow".

var flipPairs = function (string) {  return string.split("").reverse().join("");}

console.log(flipPairs("hello world"));// -> ehll oowlrd

I am trying to reverse a string in Lua without using the string.reverse() function. Here is my code -

 function reverseStr(s)   return string.gsub(s, "(.)(.)", "%2%1") end

The code is currently only reversing the first two characters in the string, and I am wondering what I can do to make the function reverse every character in the string.

abc -- cbabbc -- cbbdka -- akd

Thank you!

I just want to reverse the string order by switching the place of each index in the string.

#include <stdio.h>#include <string.h>void FirstReverse(char str[]) {    int a = strlen(str);  for(int i=0; i<strlen(str) ;i++){    str[i] = str[a-1];    a-=1;  }}int main(void) {  // keep this function call here  FirstReverse(gets(stdin));  return 0;    }
