求好串个数刚好为n个,且好串长度最大不超过k的01串数量。 子串的定义:去掉若干头部元素(可以为0个),去掉若干尾部元素(可以为0个),剩余的字符串。 10110 举例,对于上述字符串,它的好串个数为6个,分别为 1,10, 01,1 1,10 数据范围 1<=k<=n<=2500 思路 对于一个01串,我们观察它的好串个数。设...
Consider a binary string (a symmetric Bernoulli sequence) of length . For a positive integer , we exactly enumerate, in all? possible binary strings of length , the number of all runs of 1s of length (equal, at least)? and the number of 1s in all runs of 1s of length at least . ...
You are given a 0-indexed binary string s which represents the types of buildings along a street where: s[i] = '0' denotes that the ith building is an office and s[i] = '1' denotes that the ith building is a restaurant. As a city official, you would like to select 3 buildings...
How many binary strings of length 5 have exactly two 1's somewhere in the string? Do the following addition exercise by translating the numbers into 8-bit 2's complement binary numbers, performing the arithmetic, and translating the result back into a deci...
No sorting algorithm can sort n elements in better than O(n log n) time if comparing elements. However, there are other ways of sorting elements if we know some information about those elements in advance

2. Strings of length 4 There exist 16 strings τ of length 4, yielding 10 cases to be studied, since by symmetry with respect to a vertical axis, the statistic “number of τ's” for some of them (given here in pairs) are equidistributed: {uuud,uddd}, {uudd}, {uudu,dudd}, ...
Given a non negative integer number num. For every numbers i in the range 0 ≤ i ≤ num calculate the number of 1's in their binary representation and return them as an array. Example: Fornum = 5you should return[0,1,1,2,1,2]. ...

For any binary classification problem, type2. For a classification problem with more than two possible outputs, you must specify in advance the exact number of classes to count. If you enter a number that is less than the actual number of classes, the module will return an error. ...
