Find the closest pair of factors for a given number. More formally, given a number n , write it as a product of two numbers a and b such that | a - b | is the minimum of all combinations. Example For example, given a number 812848 , it can be written as the product of two numbers in the following different ways: 1 × 812848 = 812,848 2 × 406424 = 812,848 4 × 203212 = 812,848 8 × 101606 = 812,848 16 × 50803 = 812,848 101 × 8048 = 812,848 202 × 4024 = 812,848 404 × 2012 = 812,848 503 × 1616 = 812,848 808 × 1006 = 812,848 Our required answer is the last product (808 × 1006) . abs(808 - 1006) = 198 is the smallest difference among all other combinations. Approach Regardless of whether n is a perfect square, if we try to find its square root, we obtain a real root for all n ∈ R. Only considering the integer part of the square root, we can then iterate by increasing upon it with a step difference of 1 until we find a value for when the product equals given n . So, every time w...
Why the usage of Leather Jackets that keep you warm could be Paradoxical and Useless Leather is a really popular material used in various industries. Just thinking about how most of it is made got me stuck with an interesting theory. I'm not entirely sure this is accurate information, but it's just a possibility in the long run. Please give it a read! Extraction of raw material Leather is prepared from the raw-hide skin of different animals like buffalo, goat, cow, and sheep. It is recorded that from total leather exports 40 percent of buffalo and 30 percent of goat rawhide skins are used for leather. Apart from this, exotic leathers such as snake and alligator are also available. Real leather is made from the skins of dead animals (animal hide) and in many Asian countries, animals are skinned alive and doing so is not so uncommon to them. If they are fortunate enough to be killed first, they are often beaten to death, electrocuted, drowned or hanged. This also includes animal ...
