Practice Programs

Practice programs for absolute beginners. Each day a new set of program prompts is added to this repo. Students can use any language to write their solution. Please make sure to follow the guidelines below.

Guidelines

• Use any of the recommended languages to solve the problem sets.
• Flowcharts are not accepted as solutions.
• User input can be ommited for brevity.
• Orgranize your code in functions / classes.
• It is acceptable and recommended to reuse code but only within a set.
• Keep your solutions organized in a github repo.

Organization

The problems are organized in sets, each set is stored in corresponding markdown file. Each set has a list of problems, ordered in increasing difficulty that build on the previous problem.

Example

For example, for the following set

S000 by @keogami

1. Write a function to add two numbers. add(1, 2) = 3
2. Write a function that adds two arrays of number of equal lengths and returns a new array. addArray([1, 2, 3], [1, 2, 3]) = [2, 4, 6]
3. Modify the previous function to handle the case of unequal lengths. addArray([1, 2, 3], [1, 2]) = [2, 4, 3]

The following is an acceptable solution (in javascript)

const add = (a, b) => a + b // prompt 1
const addArrayEqual = (arr1, arr2) => arr1.map((val, idx) => val + arr2[idx]) // prompt 2
// prompt 3
const addArray = (arr1, arr2) => {
  const larger = Math.max(arr1.length, arr2.length)
  const result = []
  for (let idx = 0;  idx < larger; idx++) {
    result.push((arr1[idx] ?? 0) + (arr2[idx] ?? 0))
  }
  return result
}
