String Hashing¶ Hashing algorithms are helpful in solving a lot of problems.We want to solve the problem of comparing strings efficiently. The brute force way of doing so is just to compare the letters of both strings, which has a time complexity of O(min(n1,n2)) if ...
For the theory part you can visit : https://cp-algorithms.com/string/string-hashing.html about variable I use: S is length of hashed string, val1 is hash of string in mod mod1, val2 is hash of string in mod mod2. note : there is no Anti-hash yet that can hack you with this...
1.6k Last update:July 26, 2023 TranslatedFrom: e-maxx.ru This algorithm is based on the concept of hashing, so if you are not familiar with string hashing, refer to thestring hashingarticle. This algorithm was authored by Rabin and Karp in 1987. ...

I have tried to find answers on Google and the best I could find isthis problem from HackerEarth. The suggested solutions were either hashing with binary search, or suffix tree. And I am not knowledgeable enough to transform the problem into the original problem. So far the best I could ha...
You are given a binary string (consisting of 0,1) and you can rotate the string in any order. Basically if the string is s1s2s3...s(n-1)s(n) , you can make it s2s3s4,,,s(n-1)s(n)s1 . Print out the rotation which has the maximum value in binary representation. ...
