How to code this in python Write a program that computes and prints the first 1000 prime numbers - simply write out each prime number on a new line. In implementing this solution I want you to define 2 functions: is_prime which can be used to test whether a number is a prime (e.g. is_prime(17) returns True but is_prime(9) returns False) and compute_primes which will return an array (or Python list) of the first n primes where n is passed...

Write the algorithm for this program using the C++ language (not python or java). The explanation needs to be at least 250 words. Explain everything throughly step by step. While there is a built-in pop_back function in the vector class, there is no built-in pop_front function. Suppose a program needs a pop_front function that will remove the first element from the vector. For example, if the original vector is [1, 2, 3, 4, 5], then after passing in this vector...
