Write a C++ program that fills a 5 x 5 matrix of integers. The matrix must be a static matrix; its size must be fixed at compile-time. Display the contents of the matrix. Query the user for an integer. Pass the matrix and the integer to a bool function that searches for the first occurrence, and only the first occurrence, of the integer in thematrix. If the integer is found, the function returns true (and passes back the row and column coordinates of the first occurrence of the integer); if not, the function returns false. Main then displays whether the integer was found in the matrix and if so, the coordinates of the first occurrence. The use of a break to exit a loop or a function should be avoided. My code does not find the location of the first occurrence and does not use a bool function. Can you please help me to find the error. This is my code: #include <iostream> #include <random> using namespace std; int main() { int guess, array[5][5]; bool found = false; for(int…
We would like to write a collection of functions that do operations on a list of numbers. For example, suppose we write a function max_val. The function takes a list of numbers and returns the maximum value. So, if we passed the list [1,30, 70,-90,80,2] the return value would be 80, since 80 is the maximum number in the list. Here is the list of functions we would like to write: (use basic coding, loops, functions, don't use things like the sum function) 1) max_val, return maximum value. 2) min_val, returns minimum value. 3) mean, returns average. 4) std, returns standard deviation. 5) list_append, adds a new element to the end of the list. 6) list_insert, inserts a new element to the list at a desired location (do not use the insert list function). 7) list_add, adds an inputed number to every value in the list. 8) list_subtract, subtracts an inputed number to every value in the list. 9) list_multiply, multiples an inputed number to every value in the list. 10) list_divide, divides…

1. I Complete the Python function MySpline that reads in a set of x and y values (each as arrays or lists), and outputs a piecewise-cubic function with natural boundary conditions. The function prototype is cs MySpline (x, y) The returned function can be called using cs (2.4) or cs ([2.4, 3.7]), for example. You will have to find the parameter values for the as, bs, and cs so that the cubic spline can be evaluated using Pi(x)= ai-11 + ai + bk (x₁+1-x)+ ci(x − x₁), 6h₁ where hi=i+1; and i = 1,2,..., n - 1. Note that all Python indexing starts at 0, so all the indices can be decremented by 1. However, some care is needed to handle ao,..., an-1. See the documentation for MySpline for some guidance on this issue. (x+1-x)³ 6h₁ The function MySpline is already set up to return a cubic spline function. But it's not a very interesting one, and it does not pass through the points (x, y). The notebook has a small sample set of points to interpolate. Feel free to choose your own set of points.…
1. solve a system of ordinary differential equations of first order numerically using solve_ivp. 2. generate plots after "solving" the differential equations using matplotlib.pyplot. In that tutorial, the equations of motion described the dynamics of a simple pendulum. In this problem, you will investigate the motion of a satellite orbiting the Earth. This is modelled as a two-body dynamics system. A brief outline of what you need to do in this problem set is below and that is followed by a systematic set of questions towards achieving specific objectives. You will find the tutorial a handty reference here. In this problem, you will have to first create a Python function called twobody_dynamics_first_order_EOMS. Given a time t and a state vector X, this function will return the derivatives of the state vector. Mathematically, this means you are computing X using some dynamics equation X = f(t, X). Once you have this function in Python, you can solve the differential equations it…
How would I do this in Jupyter? Write a function that takes 3 numbers as input and returns the maximum amongst the 3 numbers as the output. e.g.: func_max(5, 10, 30) Maximum is 30

Please help with the bolded functions: I need to implement the following two functions that get a string, and compute an array of non-empty tokens of the string containing only lower-case letters. For example:● For a string "abc EFaG hi", the list of tokens with only lower-case letters is ["abc", "hi"].● For a string "ab 12 ef hi ", the list of such tokens is ["ab","ef","hi"].● For a string "abc 12EFG hi ", the list of such tokens is ["ab","hi"].● For a string " abc ", the list of such tokens is ["abc"].● For a string "+*abc!! B" the list of such tokens is empty. That is, we break the string using the spaces as delimiters (ascii value 32), and look only at the tokens with lower-case letters only . Q1. The function count_tokens gets a string str, and returns the number ofsuch tokens. int count_tokens(const char* str); For example:● count_tokens("abc EFaG hi") needs to return 2.● count_tokens("ab 12 ef hi") needs to return 3.● count_tokens("ab12ef+") needs to return 0. Q2. The function…
Given a vector of real numbers r = (r1, r2, ..., rm). We can standardize the vector using the formulation: vi = "im, where m ri-m is the mean of the vector r, and s is the standard deviation of r. The vector v = (v1, v2, ..., Un) will be the scaled vector. Write a Python function scale_vec (r) that takes the vector r as input and returns the scaled vector v. Sample inputs and outputs: ● Input: np.array([1, 3, 5]), output: [-1.22474487 0. 1.22474487] • Input: np. array([3.3, 1.2, -2.7, -0.6]), output: [1.35457092 0.40637128 -1.35457092 -0.40637128] Hint: Use numpy.mean and numpy.std with default parameters. # Write your function here. Let's test your function. [ ] import numpy as np print (scale_vec (np.array([1, 3, 5]))) print (scale_vec (np.array([3.3, 1.2, -2.7, -0.6])))
