Acryptographic hash takes a message as input and produces a fixed-length string as output, called the digital fingerprint. a brute force attack involves computing the hash for a largenumber of messages until a pair of distinct messages with the same hash is found. find thenumber of attempts required so that the probability of obtaining a match is ½. how manyattempts are required to find a matching pair if the digital fingerprint is 64 bits long? 128 bitslong?

In a heat transfer course, we can derive the equation for the temperature distribution in a flat rectangular plate. in this example, we will look at a plate at steadystate with three sides being held at t1, and one side held at t2. the temperature for any location on the plate, t(x, y), can be calculated by where create a function (prob3_5) that will take inputs of vectors x and y in feet, scalar n, scalars l and w in feet and scalars t1 and t2 in degrees fahrenheit. it will output a matrix t which is the temperature of each x and y locations. t will have the number of columns equal to the number of elements in x and rows equal to the number of elements in y. though this can be done without loops (perhaps more efficiently), your program must use a nested loop.
