8 Οκτ 2010 · In your code, you can test if 'test_num' is prime using the following... test_num = 23527631. if test_num < 100: checks = int(math.sqrt(test_num)) else: checks = numchecks(test_num) isPrime = all(test_num%x for x in islice(primes, 0, checks)) print 'The number is', 'prime' if isPrime else 'not prime'.
7 Σεπ 2022 · The task is to find the Nth prime number. Examples: Input : 5 Output : 11. Input : 16 Output : 53. Input : 1049 Output : 8377 . Approach: Find the prime numbers up to MAX_SIZE using Sieve of Eratosthenes. Store all primes in a vector. For a given number N, return the element at (N-1)th index in a vector. Below is the implementation of the above ...
4 Φεβ 2017 · Program to find nth Prime Number. def nth_Prime(num): Semi = num*num Res_1 = [True for i in range(Semi+1)] prime = 2 while prime*prime <= Semi: if Res_1[prime] == True: for i in range(prime*prime, Semi+1, prime): Res_1[i] = False prime += 1 Res_2 = [] for i in range(2, Semi+1): if Res_1[i]: Res_2.append(i) return Res_2[num-1] if __name__ ...
Python program to find nth prime number. Code : n = int(input('Enter : ')) prime_numbers = [2,3] i=3. if(0<n<3): print(n,'th Prime Number is :',prime_numbers[n-1]) elif(n>2): while (True): i+=1. status = True. for j in range(2,int(i/2)+1): if(i%j==0): status = False. break. if(status==True): prime_numbers.append(i) if(len(prime_numbers)==n): break.
A positive integer greater than 1 which has no other factors except 1 and the number itself is called a prime number. 2, 3, 5, 7 etc. are prime numbers as they do not have any other factors. But 6 is not prime (it is composite) since, 2 x 3 = 6 .
Given a number n, determine what the nth prime is. By listing the first six prime numbers: 2, 3, 5, 7, 11, and 13, we can see that the 6th prime is 13. If your language provides methods in the standard library to deal with prime numbers, pretend they don't exist and implement them yourself.
11 Απρ 2020 · Python - Get nth prime number. Let us try to solve the 7th problem in Euler's project which is to get the 10,001st prime number. We will start with writing a function to check if a number is prime or not. from math import sqrt. def isPrime(x): if x < 2: return False. if x == 2 or x == 3: return True.
