The base CPI of a system, excluding both memory and cache accesses, is C. Loads and stores collectively constitute LS% of all instructions Accessing the L1 data cache takes LD cycles (accounted for in base CPI). Accessing the L1 instruction cache takes LI cycles (accounted for in base CPI). Misses to main memory take an average of D cycles. The L1 D-cache miss rate/access is MD. The L1 I-cache miss rate/access is MI. Our research team tries to provide the solution to increase different characteristics of the system. First, suppose we want to improve the AMAT for our system by placing an L2 Cache with 4*LD access time. How high can be the miss rate so we can still improve the AMAT?

Write a program that prints the day number of the year, given the date in the form month-day-year. for example, if the input is 1-1-2006, the day number is 1; if the input is 12-25-2006, the day number is 359. the program should check for a leap year. a year is a leap year if it is divisible by 4, but not divisible by 100. for example, 1992 and 2008 are divisible by 4, but not by 100. a year that is divisible by 100 is a leap year if it is also divisible by 400. for example, 1600 and 2000 are divisible by 400. however, 1800 is not a leap year because 1800 is not divisible by 400.
