Q3: Superheroes Supervillains are tired of Toronto condo rental prices, so they are leaving Toronto for Mississauga. Luckily, we have n valiant superheroes that can deal with them. The i-th superhero (0 <= i < n) has a name name[i], an intelligence score in[i], and a strength score s[i]. There are m supervillains flocking to Mississauga. After thorough investigation, Detective Zingaro has determined that the supervillains can be classified into three categories for how to deal with them: A type 1 supervillain has an intelligence score int. Detective Zingaro needs to assign a superhero whose intelligence is at least as much as int to this supervillain. Moreover, to be efficient with his resources, he must assign the superhero with the minimum intelligence who satisfies this requirement. A type 2 supervillain has a strength score st. The detective needs to assign a superhero whose strength is at least as much as st to this supervillain. Similar to above, he must assign the…

Q8 Hive Minds: Migrating Birds You again control a single insect, but there are B birds flying along known paths. Specifically, at time t each bird b will be at position (x¿(t), Yb(t)). The tuple of bird positions repeats with period T. Birds might move up to 3 squares per time step. An example is shown below, but keep in mind that you should answer for a general instance of the problem, not simply the map and path shown below. Your insect can share squares with birds and it can even hitch a ride on them! On any time step that your insect shares a square with a bird, the insect may either move as normal or move directly to the bird's next location (either action has cost 1, even if the bird travels farther than one square).
Taxi zum zum def taxi_zum_zum(moves): A taxicab cruising around the Manhattan street grid starts at the origin (0,0) of the infinite twodimensional lattice grid of all pairs of integers, denoted by ℤ2. This taxicab has a direction that is always one of the four main compass directions, initially heading north. The taxicab then faithfully executes the given sequence of moves, guaranteed to be a string made up of the characters 'L' for turning 90 degrees left (while standing in place), 'R' for turning 90 degrees right (ditto), and 'F'for moving one step forward towards the current heading. This function should return the final position of the taxicab in the integer grid coordinates of this infinitely spanning Manhattan. moves expected result 'RFRL' (1, 0) 'LFFLF' (-2, -1) 'LLFLFLRLFR' (1, 0) 'FR' * 1000 (0, 0) 'FFLLLFRLFLRFRLRRL' (3, 2)
] ] is_proper You are to write a function is_proper(graph,color) that has two inputs: one a graph, and the other a labelling of the vertices, and determines whether or not the labelling is a proper vertex-coloring of the given graph. In other words, return the Boolean value True if it is, and False if it is not. After compiling the above cell, you should be able to compile the following cell and obtain the desired outputs. print (is_proper({"A": ["B", "C"], "B": ["A", "C"], "C": ["A", "B"]}, {"A": 1, "B": 2, "C": 3}), is_proper({"A": ["B", "C"], "B": ["A", "C"], "C": ["A", "B"]}, {"A": 1, "B": 1, "C": 3})) This should return True False Python Python
