#A year is considered a leap year if it abides by the

#following rules:

#

# $-$ Every $4$th year IS a leap year, EXCEPT...

# $-$ Every $100$th year is NOT a leap year, EXCEPT...

# $-$ Every $400$th year IS a leap year.

#

#This starts at year $0.$ For example:

#

# $-1993$ is not a leap year because it is not a multiple of $4.$

# $-1996$ is a leap year because it is a multiple of $4.$

# $-1900$ is not a leap year because it is a multiple of $100,$

# even though it is a multiple of $4.$

# $-2000$ is a leap year because it is a multiple of $400,$

# even though it is a multiple of $100.$

#

#Write a function called is$\_$leap$\_$year. is$\_$leap$\_$year should

#take one parameter: year, an integer. It should return the

#boolean True if that year is a leap year, the boolean False

#if it is not.

#Write your function here!
