[In C language] The concept of a "drunkard's walk" involves an individual who starts walking aimlessly from a lamp post. With each step they take, they move randomly either north, south, east, or west, each with a 25% probability. As the individual takes more steps, they tend to forget where they started and continue taking random steps. The objective is to determine how far the individual will be from the starting point (0,0) after taking N number of steps. To simulate this random walking motion for N steps, we can create a computer program. This program should ask the user to input an integer representing the number of steps to be taken. It should work for any positive value of steps, even for a large number. However, if the user enters an invalid number (such as a negative value), the program should display an error message. After each step, the program should show the current location of the random walker with respect to the origin (lamp post). Finally, when the random…
Alice, a friend of Mr. Bernard’s, wants to compose a song. She asks Mr. Bernard for help. Although Mr. Barnard knows nothing about music, he finds that the sequence of notes in a numbered musical notation can be expressed as an FSM with input the alphabet {1, 2, 3, 4, 5, 6, 7} (“do”, “re”, “mi”, “fa”, “so”, “la”, “ti”). b)Alice changes her mind. She finds that it would be enough to just use {1, 5} (“do”, “so”) in her new song. She wants to compose a song satisfying the following two conditions: i)If the sequence of notes ends with “1”, it should contain an even number of digits. ii)If the sequence of notes ends with “5”, it should contain an odd number of digits. Please draw an FSM that only accepts the sequences of notes that satisfy the above conditions.Note that you should provide a detailed description of the FSMs in your design to show how it works. Specifically, you should describe the meaning of each state
The density of an object is 2 g/cm3. To convert this to kg/m3, we need to divide it by 1000 to change grams to kilograms. Then, we need to multiply it by 10 to the power of what number to change cm3 to m3.

IN PYTHON I want a code in python and no need to post work on paper Iwant a screenshot of the code A tridiagonal matrix is one where the only nonzero elements are the ones on the main diagonal and the ones immediately above and below it.Write a function that solves a linear system whose coefficient matrix is tridiag- onal. In this case, Gauss elimination can be made much more efficient because most elements are already zero and don't need to be modified or added. As an example, consider a linear system Ax = b with 100,000 unknowns and the same number of equations. The coefficient matrix A is tridiagonal, with all elements on the main diagonal equal to 3 and all elements on the diagonals above and below it equal to 1. The vector of constant terms b contains all ones, except that the first and last elements are zero. You can use td to find that x1= −0.10557. The following code format should help: def td(l, m, u, b): '''Solve a linear system Ax = b where A is tridiagonal Inputs: l,…
