# determine maximum value in dataset
# max of dataset itself will not work because it finds the "max" list since an element in dataset is a row
# we want to find the max value of all cells in all the lists

# 1 strategy:
# get the max value of each row and make a new list of maxes
#   the max thing in the first row, the second row, ...
maxes = []

for row in dataset:
    # get the max of the current row
    row_max = max( row )
    # then append this max to our list accumulator maxes
    maxes.append( row_max )

# when we've found all the maxes in all the rows
# we get the max value of all the maxes
overall_max = max( maxes )
print( overall_max )
