Day 1: Arithmetic Operators
- A length and width are sent to two different functions
- getArea must return the area of the shape dimensions sent
- getPerimeter must return the perimeter of the shape dimensions sent
- Complete the functions
/**
* Calculate the area of a rectangle.
*
* length: The length of the rectangle.
* width: The width of the rectangle.
*
* Return a number denoting the rectangle's area.
**/
function getArea(length, width) {
let area;
// Write your code here
area = length * width;
return area;
}
/**
* Calculate the perimeter of a rectangle.
*
* length: The length of the rectangle.
* width: The width of the rectangle.
*
* Return a number denoting the perimeter of a rectangle.
**/
function getPerimeter(length, width) {
let perimeter;
// Write your code here
perimeter = 2 * (length + width);
return perimeter;
}
Day 1: Functions
- A integer of value n is provided
- 1 ≤ n ≤ 10
- Output the factorial value of n (n!, 4! = 4 x 3 x 2 x 1 = 24)
/*
* Create the function factorial here
* Recursion: To call itself is called recursion.
*/
function factorial(n) {
if (n === 0) {
return 1;
}
return n * factorial(n - 1);
}
Day 1: Let and Const
- A float value r is provided for the radius
- 0 < r ≤ 100
- Print (console.log) the area of the circle (π x r²)
- Print (console.log) the perimeter of the circle (2πr)
- Do not overwrite the try and catch but make sure the code still works
function main() {
// Write your code here. Read input using 'readLine()' and print output using 'console.log()'.
let r = readLine();
const PI = Math.PI;
// Print the area of the circle:
console.log(PI * (r * r) );
// Print the perimeter of the circle:
console.log(2 * PI * r);
}
