题目如下: Every non-negative integer N has a binary representation.  For example, 5 can be represented as "101" in binary, 11 as "1011" in binary, and so on.  Note that except for N = 0, there are no leading zeroes in any binary representa…

题目要求 Every non-negative integer N has a binary representation.  For example, 5 can be represented as "101" in binary, 11 as "1011" in binary, and so on.  Note that except for N = 0, there are no leading zeroes in any binary representat…

这是小川的第377次更新,第404篇原创 01 看题和准备 今天介绍的是LeetCode算法题中Easy级别的第238题(顺位题号是1009).每个非负整数N都具有二进制表示.例如,5可以二进制表示为"101",11可以二进制表示为"1011",依此类推. 请注意,除N = 0外,任何二进制表示中都没有前导零. 二进制表示的补码是将1改为0和将0改为1时得到的二进制数.例如,二进制中"101"的补码是二进制的"010". 对于…

题目如下: Given a number N, return a string consisting of "0"s and "1"s that represents its value in base -2 (negative two). The returned string must have no leading zeroes, unless the string is "0". Example 1: Input: 2 Output: &…

Roman to Integer Given a roman numeral, convert it to an integer. 首先介绍罗马数字 罗马数字共有七个,即I(1),V(5),X(10),L(50),C(100),D(500),M(1000).按照下面的规则可以表示任意正整数. 重复数次:一个罗马数字重复几次,就表示这个数的几倍. 右加左减:在一个较大的罗马数字的右边记上一个较小的罗马数字,表示大数字加小数字. 在一个较大的数字的左边记上一个较小的罗马数字,表示大数字减小数字.但是…

题目如下: Given a positive integer N, return the number of positive integers less than or equal to N that have at least 1 repeated digit. Example 1: Input: 20 Output: 1 Explanation: The only positive number (<= 20) with at least 1 repeated digit is 11. E…
