Tiller Test Dev Backend

Installation

Pre-requisite

• docker min version 1.12.2
• docker-compose min version 1.8.0

Docker compose

First, you will have to pull the current repository. Inside the directory execute the followings commands:

docker-compose build
docker-compose up -d

Connect to the docker

docker exec -it testback_php_1 bash

Install Symfony Env

cd /var/www/test-back
composer install

Test 1

Write a webservice that compute the sum of the numbers in a given list using a for-loop, foreach-loop, a while-loop, and recursion.

Test 2

Write a webservice that combines two lists by alternatingly taking elements. For exemple: given two lists [A, B, C] and [1, 2, 3], the results sould be [A, 1, B, 2, C, 3]

Test 3

Let's A be a matrix

A = [ 2  3  2  1 ]  Allowed moves : → or ↓
    [ 5  2  3  1 ]
    [ 1  2  2  1 ]
width = 4
heigh = 3

You can move RIGTH or DOWN. You cannot move UP or LEFT.

Write a webservice that calculate the highest path sum in a matrix following this rule (move only RIGTH or DOWN)

Test 4

Write a webservice that computes the list of the first n Fibonacci numbers. By definition, the first two numbers in the Fibonacci sequence are 0 and 1, and each subsequent number is the sum of the previous two.

As an example, here are the first 10 Fibonnaci numbers: [0, 1, 1, 2, 3, 5, 8, 13, 21, 34].

Test 5

Write a function that given a list of non negative integers, arranges them such that they form the largest possible number.

For example, given [50, 2, 1, 9] the largest formed number is 95021.

Link

Test 6

Write a program that outputs all possibilities to put + or - or nothing between the numbers 1, 2, ..., 9 (in this order) such that the result is always 100.

For example: 1 + 2 + 34 – 5 + 67 – 8 + 9 = 100. Formatted as "1+2+34-5+67-8+9".
