In c++ , perform insertion into the dynamic array at the start, end, and middle as well and perform array resizing as well. ( Drop code in words , explain the code and drop the screenshot of output as well )
: Write a small matrix library The library should have the following functions: double sumOfRow(const double mat[][MAX_COL], const int row, const int maxRow); double sumOfCol(const double mat[][MAX_COL], const int column, const int maxRow); void fillWithRandomNum(double mat[][MAX_COL], const int maxRow); void printMatrix(const double mat[][MAX_COL], const int maxRow);
Develop python program of function randomArray(m, n) that takes two integers as argument and returns a 2D m-by-n array with random elements in it. Develop python program of function adder(a1, a2) that reads two 2D arrays of the same size and returns an array that is the summation of a1 and a2. To add the two arrays, you need to add their elements, correspondingly. Develop a python program of function inverseArray(a) that takes a 2D-array as argument and inverses the array. You will need to inverse the rows, first and then inverse the columns, next. For instance, if the array = [[2, 3, 4], [5, 6, 7]], the inverse will be = [[7, 6, 5], [4, 3, 2]]
int p =5 , q =6; void foo ( int b , int c ) { b = 2 * c ; p = p + c ; c = 1 + p ; q = q * 2; print ( b + c ); } main () { foo (p , q ); print p , q ; } Explain and print the output of the above code when the parameters to the foo function are passed by value. Explain and print the output of the above code when the parameters to the foo function are passed by reference. Explain and print the output of the above code when the parameters to the foo function are passed by value result. Explain and print the output of the above code when the parameters to the foo function are passed by name.
The function ver() is defined as follows: void ver(char "pc) { char c; if( "pc == "\O' ) return; c = "pc; ++pc; ver(pc); putchar(c); Show the output when function ver() is called as follows: ver("recursion");
In java there must be at least two calls to the function with different arguments and the output must clearly show the task being performed. (ONLY ARRAYS or ARRAYLIST) Develop a function that accepts an array and returns true if the array contains any duplicate values or false if none of the values are repeated. Develop a function that returns true if the elements are in decreasing order and false otherwise. A “peak” is a value in an array that is preceded and followed by a strictly lower value. For example, in the array {2, 12, 9, 8, 5, 7, 3, 9} the values 12 and 7 are peaks. Develop a function that returns the number of peaks in an array of integers. Note that the first element does not have a preceding element and the last element is not followed by anything, so neither the first nor last elements can be peaks. Develop a function that finds the starting index of the longest subsequence of values that is strictly increasing. For example, given the array {12, 3, 7, 5, 9, 8,…
[Unbalanced Rod] Given a set of n weights {w₁,..., wn} and a rod of length n - 1 inches, we can attach the weights to the rod at hooks placed at one inch distances apart as shown in the figure below. -1". /10 2 3 12 2 4 We can attach a weight to any hook but no two weights can be attached to the same hook and we have to attach all the weights. For any given assignment of weights to hooks, we can compute the location of the center of mass of the rod and the weights according to the following equation (neglecting the weights of the rod and the hooks). where 0 ≤ Pi≤n-1 is the position of weight along the rod. For example, in the figure shown above, the center of mass is computed as C= C = i Wi Pi Σi Wi 10 0+2 1+3·2+4·3+12.4 +2.5 10+2+3+4+12+2 78 33 The problem is to find an assignment of weights to hooks that makes the center of mass as far as possible to the left, i.e., minimize the value of c. Answer the following questions. 1. Describe a greedy algorithm that finds the assignments that…

The statement int arr[size]; in the following C++ codc in Figure 5 produces an error. This is due to the size of array cannot be initialized dynamically. Thus, constant expression is required. int main () { int size, i; cin>>size; int arr[size); for (i=1; ic=size; i++) { cin>> arr[i]; cout <<"You entered : "<< arr[i]; system ("pause"); return 0; } Figure 5 Answer : Reason :
NORMALIZATION PROBLEM: Normalization is one of the most basic preprocessing techniques in data analytics. This involves centering and scaling process. Centering means subtracting the data from the mean and scaling means dividing with its standard deviation. Mathematically, normalization can be expressed as: X-X 0 In Python, element-wise mean and element-wise standard deviation can be obtained by using .mean() and .std() calls. In this problem, create a random 5 x 5 ndarray and store it to variable X. Normalize X. Save your normalized ndarray as X_normalized.npy
