Input and Output 6

 

By Roberto A. Costa Jr, UNIFEI BR Brazil

Timelimit: 1

Your teacher would like to make a program with the following characteristics:

  1. Read a number in the format: XXXXX.YYY;
  2. Print the number in inverted form: YYY.XXXXX.

 

Input

 

The inpuut consists of several test files. In each test file there is one line. The line has a real number with 3 decimal places. As shown in the following input example.

 

Output

 

For each file in the input, you have an output file. The output file has a line as described in items 2. As shown in the following output example.

Code - Javascript Programming


const { readFileSync } = require("fs")
const input = readFileSync("/dev/stdin", "utf8").split("\n").shift()

const Long = {
	/**
	 * @param { anyNumberType } numA
	 * @param { anyNumberType } numB
	 */
	min: (numA, numB) => {
		numA = BigInt(numA)
		numB = BigInt(numB)
		return numA <= numB ? numA : numB
	}
}

const DEFFAULT_VALID_MAX_VALUE_NUM = Math.pow(2, 31) - 1

/** @param { anyNumberType } originalNumber */

function revertNumParts(originalNumber) {
	return `${originalNumber}`
		.split(".", 2)
		.map(part => part.replace(/^[0]+/, "") || "0")
		.map(part => Long.min(part, DEFFAULT_VALID_MAX_VALUE_NUM))
		.reverse()
		.join(".")
