Given an array of integersnumsand an integerk. A continuous subarray is called nice if there arekodd numbers on it. Returnthe number of nice sub-arrays. Example 1: Input:nums = [1,1,2,1,1], k =3Output:2Explanation:The onlysub-arrayswith3odd numbers are [1,1,2,1]and[1,2,1,...
Given a strings, returnthe number of substrings that have only one distinct letter. Example 1: Input: s = "aaaba" Output: 8 Explanation: The substrings with one distinct letter are "aaa", "aa", "a", "b". "aaa" occurs 1 time. "aa" occurs 2 times. "a" occurs 4 times. "b" ...
Give a strings, count the number of non-empty (contiguous) substrings that have the same number of 0's and 1's, and all the 0's and all the 1's in these substrings are grouped consecutively. Substrings that occur multiple times are counted the number of times they occur. Example 1...
Explanation: There are 6 substrings that have equal number of consecutive 1's and 0's: "0011", "01", "1100", "10", "0011", and "01". Notice that some of these substrings repeat and are counted the number of times they occur. Also, "00110011" is not a valid substring because ...
828. Count Unique Characters of All Substrings of a Given String # 题目 # Let’s define a function countUniqueChars(s) that returns the number of unique characters on s, for example if s = "LEETCODE" then "L", "T","C","O","D" are the unique characters
countAndSay(1) = "1" countAndSay(n)is the way you would "say" the digit string fromcountAndSay(n-1), which is then converted into a different digit string. To determine how you "say" a digit string, split it into theminimalnumber of substrings such that each substring contains exac...
