Implement Tuple Function | LinkedIn Frontend Interview Question | JavaScript Problem Solving

In this question, you need to implement a tuple function that takes a string as input and converts it into a array of arrays. The tuple should support a function multiply that multiples ith item of each nested array.

Syntax

const item = tuple(input);

item.multiply(position);

Arguments

• input (String): the string that we need to convert

Returns

An array

Example

const input = `(1, 2, 3) , (4, 5, 6) ,  (7, 8, 9)`;

// Convert it into 
// [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
const item = tuple(input);

// Multiples 2nd item in each nested array
// i.e. 2 * 5 * 8 = 80
console.log(item.multiply(2));

The method multiply should exist on the return value of the tuple function. You can either directly set it on the return value or on the Array prototype.
