Last assignment, we had a function able to calculate the power by multiplying every time the base, which leads to the following oz function: declare fun power n m) if m-= 0 then 1 else n power n m-1) end end for example, (power 2 8) returns 256 after 8 recursive calls.
the complexity of this function is o(m), since there are m recursive calls, each responsible for one multiplication operation.

write a more efficient version of power, by reusing the intermediate results.

for example, the previous computation may be done using only 3 multiplications, namely 2-22, 2-(2) (2), 2(2 (2)

what will be the complexity of this efficient algorithm?

the answer to your question would be something called hertz. the unit of measurement called a hertz, which is one cycle per second, is used to measure clock speed. within one cycle, your computer processes, refreshes, or updates itself to the changes that it is going through. in the case of computer clock speed, one hertz equals one tick per second. the clock speed of computers is usually measured in megahertz (mhz) or gigahertz (ghz)

browsing like internet search? don't look at anything stupid. or set up restrictions on ur device's search engine. and if something suspicious comes up don't be dumb and click on it. i hope that's what ur question meant.

the today function returns a valid value without any arguments.

the today function returns the current date based on the computer's date setting and formatted as a date. today takes no parameters, but requires that you use empty parentheses
