Taking CS 201 and CS 202 Simultaneously If a student requests taking CS 201 and 202 simultaneously to stay on track to graduate on time, the following must be met. At least an A- in CS 151 Number systems (binary, octal, decimal, hex) Firm understanding of programming fundamentals - variables / data types, arrays, control flow, loops, scope, string manipulation, pointers. Ability to write basic programs in C or python - anything that can be done with a few nested control structures (loops, if’s). Review all of tutorialspoint - data structures & algorithms Good understand of the following data structures - unsorted array, sorted array, linked list, stack, queue, hash table, binary search tree. For each can do the following - explain the operations (insert, delete, lookup), run examples on the board, explain the running time of the basic operations Programming assessment - problems 1, 2, 5 correct, get problems 3 and 4 correct possibly with assistance Taking CS 201 and 303 Simultaneously To take CS 303 simultaneously, you must At least a B in CS 151 Meet items b), e), f) from the above list
