Webthis is a question given in a PDF about streaming algorithms (this isnt an assignment but im trying to understand) Exercise 4.4.1: Suppose our stream consists of the integers 3, 1, 4, 1, 5, 9, 2, 6, 5. Our hash functions will all be of the form h(x) = ax+ b mod 32 for some a and b. You should treat the result as a 5-bit binary integer. flixbus wlochy
