Question. Use Python Code Correctly to solve this problem. And, Use all Examples Please. Minimum Path Sum Given a m x n grid filled with non-negative numbers, find a path from top left to bottom right, which minimizes the sum of all numbers along its path. Note: You can only move either down or right at any point in time. Example 1: Input: grid = [[1,3,1],[1,5,1],[4,2,1]] Output: 7 Explanation: Because the path 13111 minimizes the sum. Example 2: Input: grid = [[1,2,3],[4,5,6]] Output: 12

The following equation can be used to compute values of y as a function of x: y=be¯ªsin(bx) (0.0012x¹ −0.15x³ +0.075x² +2.5x) where a and b are parameters. (a) Write Python code to compute a vector y for a = 2, b = 5, and x as a vector with values from 0 to π/2 in increments Ax= π/40. (b) Compute the vector z = y² with element-by-element-wise operations. (c) Combine x, y, and zinto a 3-column matrix W.(Hint use np. hstack function) (d) Generate a plot of y and z versus x. Include a title, axis labels, and a legend. For the y versus x curve, format a solid blue line. For the z versus x curve, choose a magenta dashed line. Include grid lines.

All information for this problem is given right here. Google “magic square" and you'll see a magic square is a square (i.e., n x n) matrix of positive integers such that the sum of each row = sum of each column = sum of the top-right to bottom-left diagonal = sum of the bottom-left to top-right diagonal. I want you to start by placing this code in your main.cpp file: // Programmer: .. // Description: Determine if a square matrix is a magic square or not. const int NUM_ROWS_COLS = 3; // Number of rows/columns in the square matrix. // Prototype for function that accepts a two-dimensional matrix of integer // values and returns "true" if the values form a magic square and "false" if not. bool IsMagicsquare (int matrix[NUM_ROWS_COLS][NUM_ROWS_COLS]); #include using namespace std; int main() { int matrix[NUM_ROWS_COLS][NUM_ROWS_COLS] = { 8, 1, 6 }, { 3, 5, 7 }, { 4, 9, 2 } }; if ( IsMagicSquare(matrix) ) { cout « "Matrix is a magic square!" « endl; else cout « "Matrix is NOT a magic…

You have an array of 10,000 subject scores for a high-school exam and you want to find the scores that are ranked from 4900 to 5100 that is the 201 most middle-ranked scores. Precisely describe two alternative algorithmic ap proaches to doing this - one of which is, in terms of time complexity, more efficient than the other.
