Title DescriptionThe number of combinations represents the number of programs that select m items from n items. For example, select two items from three items (1,3), (2,3), and three options to choose from. Based on the definition of combinatorial number, we can give a general formula for calculating the number of combinations:where n! = 1x2x XnShallot would like to know if given n,m and K, for all 0 Input/output formatInput format:The first line has two integer t,k, where T represents the total

In a set composed of n elements, order statistic is the smallest element in the set. For example, in a set composed of n elements, the minimum value is 1st sequence statistics, and the maximum value is the nth sequence statistics. The median always appears at low (n + 1)/2) or high (n + 1)/2, here, low is the downward round ("lower median"), and high is the upward round ("upper median"). When n is an odd number, there is only the "lower median ", when N is an even number, there are both "lower m

In the software system, because of the existence of a variety of character coding problems, such as another we have a very headache of Chinese problems. Therefore, it is now tending to use UTF-8 encoding as a coding format in software, thus avoiding the problem of most character encodings.
