Problem Description:Sheldon and Leonard are physicists who are fixated on the BIG BANG theory. In order to exchange secret insights they have devised a code that encodes UPPERCASE words by shifting their letters forward.
Shifting a letter by S positions means to go forward S letters in the alphabet. For example, shifting B by S = 3 positions gives E. However, sometimes this makes us go past Z, the last letter of the alphabet. Whenever this happens we wrap around, treating A as the letter that follows Z. For example, shifting Z by S = 2 positions gives B.
Sheldon and Leonard’s code depends on a parameter K and also varies depending on the position of each letter in the word. For the letter at position P, they use the shift value of S = 3P + K.
For example, here is how ZOOM is encoded when K = 3. The first letter Z has a shift valueof S = 3 × 1 + 3 = 6; it wraps around and becomes the letter F. The second letter, O, hasS = 3 × 2 + 3 = 9 and becomes X. The last two letters…

An input window which will accept the employee number and the number of days of rendered work. A 2d-arraylist that contains the employee number and the rate per day is to be searched and used to compute for the gross salary. Gross salary is computed by multiplying the number of days of rendered work by rate per day of the particular employee. If the gross salary computed is greater than 100,000 the tax is 20% of the gross salary, otherwise, the tax is 10%. Deduct the tax from the gross salary to get the net pay. Display the employee number, gross salary, tax deduction, and the net pay in an output window.

- Write this program in Java using a custom method. Implementation details You will implement this program in a specific way in order to gain some experience with loops, arrays and array lists. Use an array of strings to store the 4 strings listed in the description. Use a do-while loop for your 'game engine'. This means the game starts once the user enters money. The decision to stop occurs at the bottom of the loop. The do-while loop keeps going until the user quits, or there is no money left. The pseudocode for this 'game engine' is shown below: determine the fruits to display (step 3 below) and print them determine if there are 3 or 4 of the same image display the results update the customer balance as necessary prompt to play or quit continue loop if customer wants to play and there's money for another game.

- Fibonacci numbers are a sequence of integers, starting with 1, where the value of each number is the sum of the two previous numbers, e.g. 1, 1, 2, 3, 5, 8, etc. Write a function called fibonacci that takes a parameter, n, which contains an integer value, and have it return the nth Fibonacci number.

- Write a program that reads two matrices of integers. It then generates the sum and difference of the two matrices.  The sum of the two matrices of the same size is a matrix with elements that are the sums of the corresponding elements of the two given matrices. Addition is not defined for matrices of different sizes. If A and B are matrices of the same size, then we define subtraction as follows: A – B = A + (-B). Thus, to subtract matrix B from matrix A, we simply subtract corresponding elements.arrow_forwardWrite a program that lists all Fibonacci numbers that are less than or equal to the number k (k≥2) entered by the user. Definition:The Fibonacci sequence is a sequence of numbers in which each additional term is the sum of the previous two. It is based on the fact that each member of the sequence is formed by the sum of the previous two members, the sequence starting with the numbers 1 and 1. (Example 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233 , 377, 610, 987  write program in c languagearrow_forwardWrite a Java program that reads a list of double-precision grades (1-100) from the keyboard into an array named grade. The grades are to be counted as they’re read, and entry is to be terminated when a negative value has been entered.
