(3) since 2 is the smallest prime, for number N, we only have to go through till N/2 max., because if one number is not a prime, the other factor must be no less than 2; (4) consider N=n*m. If n<sqrt( N ), then it’s a must that m>sqrt( N ). So we only have ...
2. Algorithm to calculate prime number Please note that there is no known efficient formula (mathematically proven) to determine a number is prime or not. Generally, we can determine a number is prime or not in below steps: 2 is only prime number which is also even number. So, if given...
you only need to start at the square of the new prime. e.g. if your new prime is 5, then you don’t need to cross off 5*2, 5*3 or 5*4, because they were already done when the working primes were 2 and 3. The first number you’ll need to cross off is 5*5. Unfortunately...

But you need not worry as here are some of the easiest ways to determine whether a large number is prime or not: If there is a large number that ends with either the digits 0,2,4,6 and 8 then it is not a prime number as in all cases they are always divisible by 2 Add all ...
How to determine the cardinal number of a set? Cardinal number of a set: Cardinal number of a set is defined as the number ofdistinctelements in a finite set. For example, cardinal number of {1, 2, 4, 9, 3} is 5 cardinal number of {1, 2, 2, 4, 4, 4, 9, 3} is also 5...
Input There are a lot of cases. In each case, there is an integer N representing the number of integers to find. Each integer won’t exceed 32-bit signed integer, and each of them won’t be less than 2. Output For each case, print the number of prime numbers you have found out....
Romantic relationships, gender and sexuality are three dimensions related to sexual health issues tackled in recent TV series. We analysed what specific terms are used to refer to RRGS; and what are the other themes linked to it, in order to determine whether the references convey prosocial or...
