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)); }
