Information is transmitted over a communications channel using two signals s2 and s3. The transmittal of s2 requires 2 microseconds, and the transmittal of s3 requires 3 microseconds. A message is a finite sequence of signals, each of which is s2 or s3. Let an denote the number of different messages that can be sent in exactly n microseconds. (a) Find a recurrence relation for an.

Simon says is a memory game where "simon" outputs a sequence of 10 characters (r, g, b, y) and the user must repeat the sequence. create a for loop that compares the two strings starting from index 0. for each match, add one point to userscore. upon a mismatch, exit the loop using a break statement. assume simonpattern and userpattern are always the same length. ex: the following patterns yield a userscore of 4: simonpattern: rrgbryybgy userpattern: rrgbbrybgy

Use a physical stopwatch to record the length of time it takes to run the program. calculate the difference obtained by calls to the method system. currenttimemillis() just before the start of the algorithm and just after the end of the algorithm. calculate the difference obtained by calls to the method system. currenttimemillis() at the start of the program and at the end of the program so that the elapsed time includes the display of the result. use the value returned by the method system. currenttimemillis() just after the end of the algorithm as the elapsed time.
