C++ || Yahoo! Sports – Current Batting Order – Programming Interview Test (Question 3 of 3)

The following is sample code which demonstrates a solution to the Yahoo! Sports programming interview question titled “Current Batting Order.”

The test was taken on November 2013 for educational purposes only. Though I completed the test, at the time I had no intention of actually applying for a position, which was for the Junior Backend Test Engineer.

Given two hours, the task was to solve a total of 3 programming questions. The following is question 3 of 3. Questions 1 and 2 can be found here and here.

=== 1. INSTRUCTIONS BEFORE TAKING TEST ===

1. Why take this test? If you get all 3 questions correct you are guaranteed an interview with a Sports Engineer.

2. This is a programming test. Before you begin, Please test your environment with a sample test here.

3. Please make sure you have time free before taking the test. The test usually takes 1 to 2 hours.

4. You are free to choose any language from the list and code.

5. You're expected to write the full code. All inputs are from STDIN and output to STDOUT. If you're using Java, use the classname as 'Solution'.

6. To understand more about the environment, time limits, etc. you can read the FAQ here.

7. You can print to console to debug your code using the appropriate print command for each language (Eg: cout for C++, printf for C, etc.).

=== 2. THE PROBLEM STATEMENT ===

Question 3 / 3 (Current Batting Order)

Given the batting rosters for multiple baseball games, please output the current batting order.

Input Format:


Game Id,Team Id,Player Id, Position, Batting Order, Sub Order

Sample Input (Comments are for explanation only. They won’t be part of actual test input):

# The away team lineup starts here
331028124,24,7912,CF,1,1
331028124,24,7631,2B,2,1
331028124,24,5909,1B,3,1
# Pitcher replaces 1B in batting order
331028124,24,8394,P,3,2
331028124,24,7245,LF,4,1
# The home team lineup starts here
331028124,17,9194,SS,1,1

The pitcher replaced the first baseman in the batting order as identified by the “Sub Order” column being greater than 1. The “Sub Order” column will increment for each substitution. The highest value of “Sub Order” identifies the current batter in the game.

When given a “real” data input set, the code should display the current 9 batters for the away team followed by those of the home team. Assume the away team lineup data is always encountered first. Also assume that you will get data for more than one game.

Sample Output:

331028124,24,7912,CF,1
331028124,24,7631,2B,2
331028124,24,8394,P,3
331028124,24,7245,LF,4
331028124,17,9194,SS,1

=== 2. THE PROBLEM STATEMENT ===

Question 2 / 3 (Top 10 Fantasy Players)

Given a stream of data that contains football player statistical data, where each line represents a single player followed by several stats for that player depicted as:


Player Id,Stat A,Stat B,Stat C,Stat D

Sample Input:

9533,5,45,0,0
8573,10,120,1,0
5352,2,22,0,1
8326,1,3,1,2
9311,12,120,2,1
3343,7,20,220,0
6343,6,18,170,0
7243,2,5,100,1
PRINT

Write a program that displays the top 10 players with the greatest fantasy points based on statistical performance (in descending order of fantasy points) at any point in time. The program should display a single line of output that lists the player id along with the score for each player.

The program should print the following to standard out for each top 10 player when the input is ‘PRINT’ instead of statistical data for a player:


Player Id,Score

Use the following to score players:

2 pts for each Stat A
1 pt for each Stat B
6 pts for each Stat C
-1 pt for each Stat D

NOTE: Player Id will not be repeated. In case of a tie for fantasy points between two or more players, please sort Player Ids in descending order also. For example, output should be similar to this if two or more players (1234, 100 and 202 here) are tied on 12 fantasy points:

1234,12
202,12
100,12

Question 1 / 3 (Player IDs extractor)

Given a list of NBA play-by-play data, please extract the player ids and print them in order of appearance separated by commas.

Each line in the test case represents an NBA play and each line of the output should display the players involved in that play.

Sample Input:

[nba.p.1234] shoots the ball. Assist by [nba.p.4533]
[nba.p.4567] offensive rebound
