Chapter 8, Problem 8.23PE
(Game: find the flipped cell) Suppose you are given a 6-by-6 matrix filled with 0s and 1s. All rows and all columns have an even number of 1s. Let the user flip one cell (i.e., flip from 1 to 0 or from 0 to 1) and write a

(FYI: Pseudocode is required (Not any programming language)
Design a pseudocode program that loads an array with the following 7 values. Add one more word (of your own choosing) for a total of 8 words.
biffcomelyfezmottleperukebedraggledquisling
Be sure to use lowercase, as shown above. This will make the processing easier.
Ask the user to enter a word
Search through this array until you find a match with the word the user entered.
Once you find a match, output "Yes, that word is in the dictionary".
If you get to the end of the array and do NOT find a match, output "No, that word is not in the dictionary".
The program should work with any set of words in the arrays. If I were to change the words in the arrays, it should still work.
If you need help, look at the search example in your textbook.

Write a program that stores this information in a two-dimensional 3 × 5 array, where each row represents a different monkey and each column represents a different day of the week. The program should first have the user input the data for each monkey, or use constant values rather than asking user for input. Then it should create a report that includes the following information: Display 3X5 array first.

- Debugging challenge: Consider the code example below. This program is designed to compare the contents of two arrays: if they are equal, the program should display "TRUE," if the arrays are not equal, the program should display "FALSE". However, even when the arrays have the same value, the program always prints "FALSE", regardless of the values in arrays a and b. What is going on here? What about the program causes the comparison to always fail? int a[4] {1, 2, 3, 4}; int b[4] = {1, 2, 3, 4}; if (a == b) { display ("TRUE"); else { display ("FALSE");arrow_forwardBy using C++ program Write an application that solves a system of linear equations.

- The following program is supposed to let the end-user enters 10 numbers in a one dimensional array. The program must then check the input numbers in the following order and way: 1f the input number is a negative one, the program should multiply that number by (5), and return the number of negative elements in the array. 2. if the input number is a positive one, the program should multiply that number by (2), and return the number of positive elements in the array. 3. if the input number is a zero, the program should return the number of zeros in the array The program code is given below with some missing code. You are required to write the missing code ONLY in order to make the program complete. Sample Input/Output Enter 10 numbers in the array -8 -16 16 80 2 12 -12 -2 0 -40 -80 32 16 0 4 24 -60 -10 0 The number of negative elements is: 4 The number of positive elements is: 4 The number of zeros is: 2 dinclude using namespace std; int main() int input[10], i, negative-0, positive-0,…arrow_forwardProblem Description - JAVA PROGRAMMING Use a Two-dimensional (3x3) array to solve the following problem: Write an application that inputs nine numbers, each of which is between 1 and 10, inclusive. Display the array after the user inputs each value. Rotate/flip the array by changing places. Make the rows columns and vice versa. You have to move the elements to their new locations. Remember to validate the input and display an error message if the user inputs invalid data. Documentation and the screenshot(s) of the results.

Each number in the triangle, is constructed by adding the number above it and to the left, with the number above it and to the right. The blank entries as treated as 0. Using the recursion, implement the function that computes the Pascal’s triangle. Prarrow_forward
