A kid can hop one step, two steps, or three steps at a moment while running up a stairway with n steps. Use a technique to determine how many different methods the child can run up the steps.

Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255. Thus (255, 0, 0) is bright red, (130, 0, 130) is a medium purple, (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray). Given values for red, green, and blue, remove the gray part. Ex: If the input is: 130 50 130 the output is: 80 0 80 Find the smallest value, and then subtract it from all three values, thus removing the gray. Note: This page converts rgb values into colors.

Exercise 7 Print out if a number is prime or not from 1 to 10. Challenge (if finished) Take any number and figure out if it is prime or not another challenge on top (if finished). Keep repeating the program until the user says 'q'. I # print out if a number is prime or not from 1 to 10 # Challenge (if finished) # take any number # and figure out if it is prime or not # keep repeating the program until you say q

Python Algorithms Part 1 – Binary SearchLet's play a little game to give you an idea of how different algorithms for the same problem can have wildly different efficiencies. If I choose an integer from 1 to 16 and ask you to guess what the number is, you can keep guessing numbers until you hit on it. When you guess wrong, I tell you whether you are too high or too low. Once you've guessed the number, think about the technique you used to decide each of your next guesses.If you guessed 1, then 2, then 3, then 4, and so on, until you guessed the right number, you used an approach called “linear search,” meaning you guessed the numbers serially and sequentially, as if they were lined up in a row. This is definitely one way to find the mystery number, but it could require as many as 16 guesses. However, you could get lucky, if the number was 1, you’d only need 1 guess. Using a linear search process, on average, you'd need 8 guesses.There is an approach that is more efficient than just…
