WebTo shuffle the matrix we are going to initialize two variables: row index and col index. These are going to get a random value that lies between 0 and (number of rows, number of columns). Now we are going to swap/shuffle the matrix using a flag variable. C++ Code to shuffle matrix elements: WebSum up the weights. Generate a random number from 0 to the sum. Iterate through the objects, subtracting their weight from the sum until the sum is non-positive. Remove the object from the list, and then add it to the end of the new list. Items 2,4, and 5 all take n time, and so it is an O (n^2) algorithm.
