I am trying to create bit masks to create a new binary number with the original bits' orders turned around, and concataneted. For example, int test=0b01100010001010001001(20 bits) now, I need bit masking to make it: int result = 20th bit, 10-1 bits, 11th bit, 19-12 bits, in this order. So in this case, answer would be: 0(20th bit)10100010(10-1 bits)0(11th bit)1011000100(19-12 bits). Im trying to do something like int res |= test & 0x7F800; res |= test& 0x400; Can't seem to...

Hi I am having the following problem. At the moment I am trying to create a bode plot for the following function. G(s)=(Ks+3)/((s+2)(s+3)) Note: Not K(s+2)! I then want to plot multiple bode plots for various values of K. Eg. 1,2,3, etc. I am having two separate issues. 1. How do I define the TF with a constant K in the location required (a multiple of s in the numerator) 2. How do I create multiple bode plots for values...

In trying to apply my knowledge in the real world, I am trying to create a realistic retirement schedule. However, I am running into difficulties using both a financial calculator as well as our equations from class in doing this. I am trying to do the following: plan a retirement schedule between the ages of 25 and 70, in which I would deposit 20% of my income each year. The income starts at 80,000 with an annual growth rate of...

I am trying to create a function in JAVA that takes in an ArrayList and sorts the values by their distance in miles in increasing order. So the closest (or lowest) value would be first. It does not need to output the values in anyway, but it should return them so they can be output elsewhere. Please try to use the stub class below. The code for the main class is not necessary. I am only really asking for the...

I am trying to create a method in JAVA that takes in an ArrayList and sorts it by the requested "amenities" that a property has. So if someone wants a "pool" and "gym" it would show all members of the array that contain a "pool" and "gym". It does not need to output the values in anyway, but it should return them so they can be output elsewhere. Please try to use the stub class below. You can edit it...

I am trying to create a method in JAVA that takes in an ArrayList<Property> and filters it by the requested price range that a property has. So if someone wants a property between the value of 10(min) and 20(max) it would show all members of the array that meet those conditions.. It does not need to output the values in anyway, but it should return them so they can be output elsewhere. Please try to use the stub class below....

I am trying to create a method in JAVA that takes in an ArrayList<Property> and sorts it by the amount of "reviews" that a property has in increasing order. So the most reviews first. So each listing in the array would contain a different number of reviews, and they should be sorted based on that value. It does not need to output the values in anyway, but it should return them so they can be output elsewhere. Please try to...

I am trying to create a program that reads from a csv file and finds the sum of total volume in liters of liquor sold from the csv file by county and print that list out by county in descending order. Currently my program runs and gives me the right answers but it is not in descending order. I tried this: for county, volume in sorted(sums_by_volume.items(), key=lambda x: x[1], reverse=True): index +=1 print("{}. {} {:.2f}".format(county, sums_by_volume[county])) When I run...
