java Seasons Write a program that takes a date as input and outputs the date's season. The input is a string to represent the month and an integer to represent the day. The program stops when input is Quit 0. Ex: If the input is: April 11 the output is: Spring In addition, check if the string and int are valid (an actual month and day). Ex: If the input is: Blue 65 the output is: Invalid The dates for each season are: Spring: March 20 - June 20 Summer: June 21 - September 21 Autumn: September 22 - December 20 Winter: December 21 - March 19

The instruction ishl (shift left integer) exists in jvm but not in ijvm. it uses the top two values on the stack, replacing the two with a single value, the result. the sec- ond-from-top word of the stack is the operand to be shifted. its content is shifted left by a value between 0 and 31, inclusive, depending on the value of the 5 least signifi- cant bits of the top word on the stack (the other 27 bits of the top word are ignored). zeros are shifted in from the right for as many bits as the shift count. the opcode for ishl is 120 (0x78).a. what is the arithmetic operation equivalent to shifting left with a count of 2? b. extend the microcode to include this instruction as a part of ijv.

Least square fit to polynomial write a function leastsquarefit3pol that solves a linear system of equations to find a least squares fit of a third order polynomial to an experimental data set given as two row arrays. the function leastsquarefit3pol must explicitly solve a set of linear equations and cannot use polyfit. there should be no restriction on the size of the problem that can be solved.
