Hippity hoppity, abolish loopity def frog_collision_time(frog1, frog2): A frog hopping along on the infinite two-dimensional lattice grid of integers is represented as a 4- tuple of the form (sx, sy, dx, dy) where (sx, sy) is its starting position at time zero, and (dx, dy) is its constant direction vector for each hop. Time advances in discrete integer steps 0, 1, 2, 3, ... so that each frog makes one hop at every tick of the clock. At time t, the position of that frog is given by the formula (sx+t*dx, sy+t*dy) that can be nimbly evaluated for any t. Given two frogs frog1 and frog2 that are guaranteed to initially stand on different squares, return the time when both frogs hop into the same square. If these two frogs never simultaneously arrive at the same square, return None. This function should not contain any loops whatsoever. The result should be calculated using conditional statements and integer arithmetic. Perhaps the best way to get cracking is to first solve a simpler…

Design and implement a backtracking algorithm that checks to see if two simple graphs are isomorphic. The algorithm must print “not isomorphic”, if the two graphs are not isomorphic. The algorithm must print “isomorphic” and the orderings of the vertices for which their adjacency matrices are equal, if the graphs are isomorphic. Test your implemented algorithm with the three test cases in Project3_TestCases.

Lists – Lists can be encoded in the lambda calculus. A way to do this, is by defining alambda term that, like a "cons", inserts an element at the head of a list, initially empty. Ratherthan showing the full lambda term, we introduce the defined term cons. For example, theresult of reducing the encoding of the expression cons 3 [7, 8] will be the encoding for thelist [3, 7, 8] .Assume that you have available the fixed-point operator Y and the termscons, sqr and succ , respectively for list construction, square and successor functions.Which expressions will these terms define? Show your argument before the final answer.1. Y λl.(cons x l)2. Y (λf.λn.(cons (sqr n)(f(succ n)))) 0
