computer science OBJECTIVE

Create a flowchart using the Diagram tool to solve a quadratic equation in the form $a{x}^2+bx+c=0$

REQUIREMENTS

The program shall validate the user's inouts, print the equation to solve, solve the equation, and print the results.

The program logic shall accommodate the following conditions

Nosolution

One solution

Two solutions

Complex solutions $($these solutions involve the complex number i$)$

HINTS

Focus on the logic" of what needs to be done and account for every possibility.

Use the Diagram tool that we had discussed in class.

Represent the conditions for testing the user inguts and ask the user to re$-$enter any invalid input.

Label decision elements with Yes$/$No$.$

Don't show equations or programming statements in the flowchart, just the steps and the logic

Make all flowchart elements line up and acrange them symmetrically. Focus on readability, use colors, and avoid crossing lines.

Design, code, and test a $C$ program that uses dynamic programming to determine two separate subsequences of the input such that the first subsequence sums to the first target value and the second subsequence sums to the second target value.

The input should be read from standard input $($which will be one of $1.$ keyboard typing, $2.$ a shell redirect $)<mi\; id="EditorElement\_2640359">(</mi>$ from a file, or $3.$ cut$-$and$-$paste. Do NOT prompt for a file name!$).$ The first line of the input will give $n,$ the length of the sequence, along with the two target values. Each of the remaining input lines will include one sequence value. All values will be positive integers.

Your program should echo the target values and the input sequence. If a problem instance has a solution, each of the two subsequences should be output. Each value is to be preceded by its index in the input. A message should be provided for instances without a solution.

Lab Challenge $-$ Chessboard

Loops Challenge

For this challenge, you will output a pattern that resembles a chessboard by using the letter $x$ and $0.$ The pattern needs to be an $88$ matrix with alternating $x$ and $0$ in each row. Here is the catch, you must also ensure that alternate rows start with a different letter than the previous row.

Here is the required output.

You should make use of a looping structure in combination with a decision structure to achieve this result. Also, by default, Python's print$()$ function will add the newline character at the end of each print$()$ function so to ensure that this newline does not create a long, single column output of the letters, use this syntax for your print$()$ functions, print$(\text{'}x\text{'},$ end$=\text{'}\text{'}).$ Note the use of$,$ end$=\text{'}\text{'}$ after the letter to output.
