There are 5 rows and 3 columns for the matrix Scores. Now since matrix is a form of 2 dimensional arrays in computer, which starts from 0, the row can be - 0 ,1, 2,3,4 and column- 0,1 ,2 .
Scores [0] [0] means 1st row and 1st column of the matrix which is 86 (see the first row in question)
Scores [5] [2] is junk because 5 means 6th row which isnt present in the given matrix.
Scores [2] [1] simply stores the value in 3rd row at 2nd column
