Write a code named gd. m to implement gradient descent algorithm for the logistic regression problem (1) using the constant step-size scheme. the input for gd. m should include xtr, ytr, yte, yte, the regularization parameter λ, and the constant step-size t. the output for gd. m should be the training error, test error and the objective value at each iteration.
the code should appropriately address two critical issues:
i) how do you choose the constant step-size t?
ii) when do you think to stop the iteration process in your gd algorithm such that its iterative output is guaranteed to be sufficiently close to the optimal solution?

Write a program that begins by reading in a series of positive integers on a single line of input and then computes and prints the product of those integers. integers are accepted and multiplied until the user enters an integer less than 1. this final number is not part of the product. then, the program prints the product. if the first entered number is negative or 0, the program must print “bad input.” and terminate immediately
