Test case 1 say s = 999 and k = 1 so the choice would be 9,99 or 99,9 in either case the maximum number is 99 Test case 2 say s=999 and k =2 so the choice will be like 9,9. Input Format. That means 95,676,260,903,887,607 primes (nearly 10 17), but they were not stored.There are known formulae to evaluate the prime-counting function (the number of primes below a given value) faster than computing the primes. The Euclid-Mullin sequence is the sequence that starts 2, 3, 7, 43, 13, and so on: the first term is 2, and each subsequent term is the smallest prime factor of 1 plus the product of all previous . For instance, a 8 = 2(8) + 3 = 16 + 3 = 19.In words, "a n = 2n + 3" can be read as "the n-th term is given by two-enn plus three". Kevin Ford has obtained upper bounds of the expected order of magnitude on this quantity as well as lower bounds in a special case of the parameters y and z. That is, g (pn) is the (size of) gap between pn and pn+1. $\begingroup$ Every string should be contained in some prime. I expect there's no way to get the exact answer, but is there a way to get at least an order of magnitude of the goal prime so I can skip to brute forcing on the right magnitude? Repeating Sub-Sequence 300 64:11 Distinct Subsequences 325 .
