Task:
Given an array,A, of N integers, print A’s elements in reverse order as a single line of space-separated numbers.
Solution:
1)Javscript:
'use strict';
process.stdin.resume();
process.stdin.setEncoding('utf-8');
let inputString = '';
let currentLine = 0;
process.stdin.on('data', function(inputStdin) {
inputString += inputStdin;
});
process.stdin.on('end', function() {
inputString = inputString.split('\n');
main();
});
function readLine() {
return inputString[currentLine++];
}
function main() {
const n = parseInt(readLine().trim(), 10);
const arr = readLine().replace(/\s+$/g, '').split(' ').map(arrTemp => parseInt(arrTemp, 10));
console.log(...arr.reverse());
}
