Have an array that needs sorting? Perhaps you have a range of condominiums and you want to know the highest and lowest priced properties? Check it.
# here's my array
@condo_prices = [1000, 75, 2000, 10000]
# returns 75
@condo_prices.min
# returns 10000
@condo_prices.max
@condo_prices = [1000, 75, 2000, 10000]
# returns 75
@condo_prices.min
# returns 10000
@condo_prices.max
