Day 2: Conditional Statements: If-Else | 10 Days of JavaScript | HackerRank Solution

Hello coders, today we are going to solve Day 2: Conditional Statements: If-Else HackerRank Solution which is a part of 10 Days of JavaScript Series.

Objective

In this challenge, we learn about if-else statements. Check out the attached tutorial for more details.

Task

Complete the getGrade(score) function in the editor. It has one parameter: an integer, score, denoting the number of points Julia earned on an exam. It must return the letter corresponding to her grade according to the following rules:

• If 25 < score <= 30, then grade = A.
• If 20 < score <= 25, then grade = B.
• If 15 < score <= 20, then grade = C.
• If 10 < score <= 15, then grade = D.
• If 5 < score <= 10, then grade = E.
• If 0 < score <= 5, then grade = F.

Input Format

Stub code in the editor reads a single integer denoting score from stdin and passes it to the function.

Constraints

• 0 <= score <= 30

Output Format

The function must return the value of grade (i.e., the letter grade) that Julia earned on the exam.

Sample Input 0

11

Sample Output 0

D

Explanation 0

Because score = 11, it satisfies the condition 10 < score <= 15 (which corresponds to D). Thus, we return D as our answer.

Solution – Day 2: Conditional Statements: If-Else

'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 getGrade(score) {
    // Write your code here
    if(score > 25 && score <= 30){
        return("A");
    }else if(score > 20 && score <= 25){
        return("B");
    }else if(score > 15 && score <= 20){
        return("C");
    }else if(score > 10 && score <= 15){
        return("D");
    }else if(score > 5 && score <= 10){
        return("E");
    }else if(score > 0 && score <= 5){
        return("F");
    }
    
    return grade;
}


function main() {
    const score = +(readLine());
    
    console.log(getGrade(score));
}
