If is negative, throw an Error with Negative Error .

Input Format

Locked stub code in the editor reads the following input from stdin and passes each value of to the

function as an argument:

The first line is an integer, , denoting the number of times the function will be called with some .

Each line of the subsequent lines contains an integer denoting some .

Sample Output 0

YES

YES

YES

Explanation 0

Each of the given values is positive, so we return YES each time. The value returned during each function

call is printed on a new line by locked stub code in the editor.

Sample Input 1

2

0

6

Sample Output 1

YES

Zero Error

YES

Explanation 1

Locked stub code in the editor makes the following three calls to the isPositive function:

1. isPositive(2): This returns YES because is positive.

2. isPositive(0): Because , we throw an Error with Zero Error . This is caught by the

locked stub code and the value of its is printed.

3. isPositive(6): This returns YES because is positive.

Sample Input 2

2

-1

20

Sample Output 2

Negative Error

YES

Explanation 2

Locked stub code in the editor makes the following two calls to the isPositive function:

1. isPositive(-1): Because , we throw an Error with Negative Error . This is caught

by the locked stub code and the value of its is printed.

2. isPositive(20): This returns YES because is positive.

 

Solution:

'use strict';      process.stdin.resume();     process.stdin.setEncoding('utf-8');      let inputString = '';     let currentLine = 0;      process.stdin.on('data', inputStdin => {     inputString += inputStdin;    });      process.stdin.on('end', _ => {     inputString = inputString.trim().split('\n').map(string => {         return string.trim();     });         main();       });      function readLine() {     return inputString[currentLine++];   }    function isPositive(a) {           if(a>0){            return "YES";               }                          throw Error(a ?"Negative Error":"Zero Error");       }        function main() {     const n = +(readLine());         for (let i = 0; i < n; i++) {         const a = +(readLine());               try {             console.log(isPositive(a));         } catch (e) {             console.log(e.message);         }        }    }
