The dictionary accumulates modulating integers.s

• Modulo division can be a way to loop through a list of numbers without needing a for loop. For examples, using %100 to rotate through a list of numbers from 0-99.
• Integer division can be used to check the number of times a list of numbers loops through a certain number, without needing a for loop. For example, using //100 to count the number of times 0 has been looped through in a list of numbers from 0-99.
• Use itertools.accumulate to perfom accumulation on a list of numbers
• Dictionaries, such as {'L':-1, 'R':1}, can be used to replace if/elif blocks
