In this article, we are going to find number of strings that can be formed under given constraints. This is a pure combinatorial problem that was featured in Google interview.
Learn how to effectively replace two substrings of a string with each other using various programming techniques. Explore code examples and detailed explanations.
We are not at all bothered how many zeros are in between those two '1'. In fact, there can be '1's in between those two '1's picked up.Thus, number of substrings starting with '1' & ending with '1' , where count is the frequency of '1's in the string. ...
Give a string s, 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....
Write C++ a function that determines if two strings are anagrams. The function should not be case sensitive and should disregard any punctuation or spaces. Two strings are anagrams if the letters can Determine the number of comparisons (as a function of n and m) that are performed in mer...
在Python中查找所有子串的含有同字异序词的位置 假设有一个只包含小写字母的字符串s。我们需要找出在s中存在另一个不同位置的子串是以取出的子串排列组合而成的(即为同字异序词)。我们要按字典顺序找出子串列表。 例如,如果输入为s=”abcba”,则输出为[‘a’, ‘a’, ‘ab’, ‘abc...
