Problem: https://www.hackerrank.com/challenges/breaking-best-and-worst-records/problem
C# Language Version: 6.0
.Net Framework Version: 4.7
Tool Version : Visual Studio Community 2017
Thoughts :
1. Let the count of minimum and maximum records broken be cmin and cmax. Initially, set cmin and cmax to 0.
2. If total number of games is 1 then jump to step 4.
3. If total number of games is greater than 1 then a processing is reequired as below:
3.1 Let the mininum and maximum score record be gameMin and gameMax. Set gameMin and gameMax to score of first game.
3.2 Start iterating the scores starting from second game onwards:
    3.2.1 If score of current game is less than gameMin then increment cmin by 1 and set gameMin to current game score.
    3.2.2 If score of current game is greater than gameMax then increment cmax by 1 and set gameMax to current game score.
    3.3.3 Process all the game scores by following steps 3.2.1. through 3.2.2.
4. Print cmin and cmax on same line separated by a space.

Time Complexity:  O(n)
Space Complexity: O(1)
