But the Codeforces rating system could become broken. So, I propose that we can have two separate rating systems. Virtual rating: applies to all users. Verified-human rating: only those who participate in onsite contest and perform on Codeforces online contests at a similar level as they perfor...
LeetCode Topcoder SRM Notable sponsors of contests include global companies (e.g., Meta, Google—at least, this was true until the project was sunset in July 2023) and organizations for students (e.g., ICPC, IOI). Additionally, groups such as UVa Online Judge and Project Euler support th...
Output: “ABC” Example 2: Input: str1 = “ABABAB”, str2 = “ABAB” Output: “AB” Example 3: Input: str1 = “LEET”, str2 = “CODE” Output: “” Note: 1 <= str1.length <= 1000 1 <= str2.length <= 1000 str1[i] and str2[i] are English uppercase letters. GCD of...

map, or simply – a two dimension counter table. The first run is to count the frequency of 26 letters for each string. The second run thus is to find the common letters by iterating over each character and check each string. The minimal number will be used to push to the result ...
It did pretty well on the easy level of the Leetcode (31 out of 41 problems solved) but struggled when it came to medium or hard level of difficulty (21/80 and 3/45 respectively). As we saw in thedeveloper demo livestream, GPT-4 is fully capable of writing Python, but required som...
Many programming languages provide the inbuilt stringsplitfunction that allows you tosplita string into array of strings by a set of delimiters. For example, using Python3, you can solve this problem by the following code: 1 2 3 4
