In this challenge, the given REST API contains information about football matches played in the years 2011-2015.
Given a year and integer k, denoting the minimum number of matches we are interested in, your task is to use the API to get the names of teams that played at least k matches in the given year in the competition named UEFA Champions League. The names must be returned as an array and ordered in ascending order.
The given API uses pagination to return the data divided into pages. Fetching the whole data available on the API requires multiple requests.
To get a single page of matches played in UEFA Champions League in the given year, perform HTTP GET request to:
https://jsonmock.hackerrank.com/api/football_matches?competition=UEFA%20Champions%20League&year=&page=
where denotes the year of the match and is an integer denoting the page of the results we are requesting.
For example, a GET request to
will return page 2 of the collection of matches played in the UEFA Champions League in the year 2011. Pages are numbered from 1, so in order to access the first page, you need to ask for page number 1.
The response to such request is a JSON with the following 5 fields:
page: The current page of the results. per_page: The maximum number of matches returned per page. total: The total number of matches on all pages of the result. total_pages: The total number of pages with results. data: An array of objects containing matches information on the requested page
Each match record has several fields, but in this task only these two are relevant:
team1: The name of the first team in the match. team2: The name of the second team in the match.
It is guaranteed that there exists at least one team that will be included in the resulting array.
Function Description
Complete the function getTeams in the editor below.
getTeams has the following parameters:
int year: the year being queried
int k: the minimum matches that a team must have played during the given year to be included in the result
Returns:
string[]: an array denoting the names of teams that played at least k matches in the UEFA Champions League in the given year, returned in ascending order
Implement a function processOrderList that:
takes 3 arguments: an order list orderList, a number orderId, and a string state that is either "Processing" or "Delivered". orderList is an array of order objects. An order object has the following schema: { id: Number, state: String } updates the order list depending on the state and returns the updated list. If the state is 'Processing', it updates the object in the list having id as orderId, to have the state 'Processing'. If the state is 'Delivered', it deletes the object from the list having the id of orderId. If there is no order with the given orderId then the function returns the list orderList unchanged.
NOTE: You can assume that initially, all orders in the list have a state of 'Received'.
The implementation will be tested by a provided code stub and several input files with parameters. The function will be called and the result printed to the standard output by the provided stubbed code. The stubbed code first creates a list of orders in Received state. The status of all orders in the updated order list are printed after all the operations are completed. If the final list is empty, the stub code prints 'All orders are in Delivered state'
