WebThe prime number theorem gives an approximation to π ( n), the number of primes less than n. You can subtract the values at the start and end of an interval. Mathematica and other software can compute exact values for small values of n and approximate values for larger values of n. Webanswer has a name: π(x) = the number of primes less than or equal to x. The primes under 25 are 2, 3, 5, 7, 11, 13, 17, 19 and 23 so π(3) = 2, π(10) = 4 and π(25) = 9. (A longer …

Web7 sep. 2024 · First, except for the number 2, all prime numbers are odd, since an even number is divisible by 2, which makes it composite. So, the distance between any two prime numbers in a row (called successive prime numbers) is at least 2. In our list, we find successive prime numbers whose difference is exactly 2 (such as the pairs 3,5 and 17,19). WebThe first line contains a single positive integer, n ( 1 ≤ n ≤ 105 ), showing how many numbers are in the array. The next line contains n space-separated integers xi ( 1 ≤ xi ≤ 1012 ).
