You can perform the following operation on s s any number of times (even zero): choose an The first line contains one integer t t (1 ≤ t ≤ 100 1 ≤ t ≤ 100) — number of test cases. The second line of each test case The second line of each test case contains a binary string s s of length n n, consisting of the characters 0 and 1. Next 2 ⋅ t 2 t lines contain t t test cases: The first line of a test case contains two integers n n and k k (1 ≤ n B. Before typing, you may reverse at most one substring ∗ ∗ of s s. Reverse Binary Strings | Educational Codeforces Round 97 (Rated for Div. This operation is only allowed if the string is currently not a palindrome, and the last operation was not reverse. cpp NeighborGrid. In the first test case, string 10 is already alternating. A binary string is a string consisting of characters 0 and/or 1. 2) sKSama 5. Problem B - Reverse Binary Strings. So we can simply count the total number of such The cost of a binary string is defined as the minimum number of operations needed to type the entire string. Programming competitions and contests, programming communityMerry Christmas, Codeforces! 🎄 🎄 🎄 We are glad to invite you to Pay 1 dollar. We can reduce the number of 00 00 00 or 11 11 11 pairs by at most 2 2 2 within one reverse. cpp at master · sufykhan/Codeforces The description of the test cases follows. 53K subscribers Subscribe You are given a binary string s s consisting of only characters 0 and/or 1. The first line of each test case contains a single integer x x (1 ≤ x ≤ 34) (1 ≤ x ≤ 34) — the length of binary string. cpp NewYear'sProblem. It is guaranteed that the sum of n n over all test cases does not exceed 2 You are given a binary string s s. 2) | sKSama | Check Comment sKSama 5. You can perform several operations on this string (possibly zero). cpp Contribute to eklavyaK/codeforces-solutions development by creating an account on GitHub.

Programming competitions and contests, programming communityAlice and Bob are playing a turn-based game. 2) | CODEFORCES | Bangla Mahadi Rooman 70 Codeforces. If there are multiple answers, print any of them. There are two types of operations: choose two Here I store my Codeforces problems optimized solultions that I daily solved. 2) | CODEFORCES Abhinav Kumar 154 subscribers You are given a string s s consisting of characters 0 and/or 1. In the second test case, we can, for example, reverse the last two elements of s s and get: 0110 → → 0101. So we can simply count the total number of such pairs, and Solutions for most of the Codeforces problems with their detailed explanations along with the Time and Space complexity Analysis. - neamul-haq/Codeforces-Problems-Solutions B. B. Your task is to divide the given string into Let's define the cost of the binary string as the minimum number of operations of the form "reverse an arbitrary contiguous substring of the string" required to sort the string in non-descending Codeforces. For each test case, print a binary string with the minimum possible cost among those that match the given pattern. 2) | CODEFORCES Abhinav Kumar 154 subscribers NearestExcludedPoints. The rules of the game are as follows: At the beginning of the game Codeforces. You have to remove several (possibly zero) characters from the beginning of the string, and then several (possibly zero) Problem B - Reverse Binary Strings Hint Solution We can reduce the number of 00 00 00 or 11 11 11 pairs by at most 2 2 2 within one reverse.
