In this task, you have to implement the loadGameRecord$($String$)$ method. The method loads all the game records from a text file via a given java.io$.$Reader object and stores these records into a GameRecord array. Each line in the text file contains the name, level and score fields of a single game record and these fields are separated by a tab character, $\text{'}\backslash$t$\text{'}.$ After reading the entire file, a GameRecord array containing all the game records is returned. Note that the size of the GameRecord array returned should be exactly the same as the number of non$-$empty records in the text file.
