Write a program which takes 2 digits, X,Y as input and generates a 2-dimensional array. The element value in the i-th row and j-th column of the array should be i _ j Note: i=0,1,···, X-1; j=0,1,···,Y-1. Suppose the following inputs are given to the program: ...
Write a Python program to print all primes (Sieve_of_Eratosthenes) smaller than or equal to a specified number. In mathematics, the sieve of Eratosthenes, one of a number of prime number sieves, is a simple, ancient algorithm for finding all prime numbers up to any given limit. It does ...

A simple Python program to solve this problem as follows: term = int ( input (‘Enter the term of the value to be determined: ‘)) n = nth = 1 while nth < term: if n<10: # 1 digit n = n + n elif n<100: # 2 digits ...
On the lab (Windows) machines, this is done via Start -> Anaconda Prompt (type this into the search field to locate the program). Your TA will help you with this. If on your own machine, install Python and Jupyter by installing Anaconda (Python 3.x version). Anaconda conveniently ...
In the main part of your program, outside of the performTest function, write some code that asks the user for their name, and whether they would like to practice subtraction or exponentiation. Then ask how many practice questions they’d like (if they say 0, then your code should not as...
