If we were given a vector of numbers, say [10, 2, 5, 8, 45, 2, 6], here the number 2 repeats, and we have to use it 2 times only since it’s present in the array two times. Prime number A prime number is an integer greater than 1 whose only factors are 1 and itself. For example, to generate the sequence of multiples of some number n, just take P = 1, Q = n, and initial value 0. One of the key advantage of python over other programming language is that it comes with huge set of libraries with it.
