Canada ( /ˈkænədə/) is a North American country consisting of ten provinces and three territories. Located in the northern part of the continent, it extends from the Atlantic Ocean in the east to the Pacific Ocean in the west, and northward into the Arctic Ocean. Spanning over 9,900,000 km2 (3,800,000 sq mi), Canada is the world's second-largest country by total area, and its common border with the United States is the longest land border in the world.
The land that is now Canada has been inhabited for millennia by various Aboriginal peoples. Beginning in the late 15th century, British and French colonial expeditions explored, and later settled, along the region's Atlantic coast. France ceded nearly all of its colonies in North America in 1763 after the Seven Years' War. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces and territories and a process of increasing autonomy; the Canada Act 1982 severed the vestiges of legal dependence on Britain.
In mathematics, big O notation is used to describe the limiting behavior of a function when the argument tends towards a particular value or infinity, usually in terms of simpler functions. It is a member of a larger family of notations that is called Landau notation, Bachmann–Landau notation (after Edmund Landau and Paul Bachmann), or asymptotic notation. In computer science, big O notation is used to classify algorithms by how they respond (e.g., in their processing time or working space requirements) to changes in input size.
Big O notation characterizes functions according to their growth rates: different functions with the same growth rate may be represented using the same O notation. A description of a function in terms of big O notation usually only provides an upper bound on the growth rate of the function. Associated with big O notation are several related notations, using the symbols o, Ω, ω, and Θ, to describe other kinds of bounds on asymptotic growth rates.
Big O notation is also used in many other fields to provide similar estimates.
John Marwood Cleese (/ˈkliːz/; born 27 October 1939) is an English actor, comedian, writer and film producer. He achieved success at the Edinburgh Festival Fringe and as a scriptwriter and performer on The Frost Report.

In the mid 1970s, Cleese and his first wife, Connie Booth, co-wrote and starred in the British sitcom Fawlty Towers. Later, he co-starred with Kevin Kline, Jamie Lee Curtis and former Python colleague Michael Palin in A Fish Called Wanda and Fierce Creatures. He also starred in Clockwise, and has appeared in many other films, including two James Bond films as R/Q, two Harry Potter films and three Shrek films.
With Yes Minister writer Antony Jay he co-founded Video Arts, a production company making entertaining training films.
