l2-005. Set similarity time limit MS Memory limit 65536 KB code length limit 8000 B award Program StandardAuthor ChenGiven a collection of two integers, their similarity is defined as: nc/nt*100%. Where NC is the number of unequal integers in all two sets, NT is the number of unequal integers that have a total of two sets. Your task is to calculate the similarity of any given set.Input format:Enter the first line to give a positive integer n (The line then gives a positive integer k (Output form

Cosine similarity degree

Title Description: Give you two vectors of the same size a B, to find their cosine similarity; returns 2.0000 if the cosine is similar to a non-method (e.g. A = [0] B = [0]).Example: Given a = [1, 2, 3], B = [2, 3, 4].Returns 0.9926, given a = [0], B = [0]. Returns 2.0000Python calculates this kind of data science is juchongruoqing, even without any third-party library, can be very concise code to complete the operation.Calculating the cosine of two vectors is an important method to judge the si

Nine degree OJ1184 two fork tree

Title Description: A program that reads a string of first-order traversal strings of user input and establishes a binary tree (stored as a pointer) based on this string.For example, the following is an ordinal traversal string:abc# #DE #g# #F # # #Where "#" represents a space, an empty characters represents an empty tree. After this binary tree is established, the sequential traversal of the two-fork tree is performed, and the output traversal results are obtained.

In-depth understanding of computer systems (2.6)---Multiplication and division operations of binary integers (important) "high degree of difficulty"

not difficult to understand, we assume x = KY + R (we consider r > 0, there will be rounding occurring), then there is.└ (x+y-1)/y┘=└ (ky+r+y-1)/y┘= K +└ (r+y-1)/y┘= K + 1You can see that after doing this processing, that is, the X plus y-1 offset, at this time in the rounding, the result will be added 1 on the original basis. This is exactly what "biasing" means, and it will round out the rounding "offset".Here we will complement the division of the program in this way to fix it, see if this i

Title Description: Enter a sequence of two integers, and the first sequence represents the stacking order of the stack, judging whether the second sequence is the pop-up order for the stack. Assume that all the numbers that are pressed into the stack are not equal. For example, the sequence 1,2,3,4,5 is the indentation order of a stack, and the sequence 4,5,3,2,1 is a pop-up sequence corresponding to the stack sequence, but 4,3,5,1,2 is not likely to be the pop-up sequence of the
