Write a function, called remove$\_$dups, that takes a list of tuples and removes

any

# duplicate tuples and returns the modified list. Cannot use built$-$in functions nor

# sets.

# For example if the list contains $[(1,2),(1,4,5),(1,2),(3,5)]$ then the

list

# will become $[(1,2),(1,4,5),(3,5)].$

# $(10$ points$)$
