How about Apple's 27-inch retina imac?

Apple will soon launch its new imac with a 27 "5K" Retina display next month with a resolution up to 5120x2880. A source familiar with Apple's plans tells us that Apple is indeed planning to launch a Retina imac at its next press conference, but the model is limited to 27 inches. The new 27-inch imac would use 5120x2880 resolution, the source said, and the code for the US-OS X-U had leaked that resolution a few months ago. The new imac resolution is

Loj 6165. A water problem (linear sieve)

Title Description Transmission Door The main idea is to find the smallest integer that can divide [1,n] into 100000007. Solving is actually to ask for the least common multiple in [1,n], least common multiple equals ∏pimax (QI) \prod Pi^{max (QI)}That is, the product of the maximum power of all the mass factors.Just beginning to think that the 108 10^8 linear sieve can not be, but the loj of the evaluation machine is faster, all directly do the co

Number of 0 of the mantissa of the integer factorial result

the factor "5" in the factorization of a number does not necessarily correspond to a "0", because a factor of "2" is required to achieve its one by one counterpart.Let's go back to the original question. Here is a first conclusion:Conclusion 1: For the factorial n! of n , in its factorization, if there is a factor "5", then it must correspond to the n! A "0" at the end.The following is a proof of this conclusion:(1) when n (2) when n >= 5 o'clock, make n! = [
