the sign of each next element is the opposite from the sign of the current element, like In this video, we dive into Problem 8: Alternating Subsequence and provide a detailed video editorial to help you enhance your problem-solving skills. Here, we define an alternating subsequence of a string as a not-necessarily contiguous subsequence where no two consecutive elements are equal. We will discuss the entire problem step-by-step and work towards developing an opt Codeforces. For each day he decides if it was good or bad. AkeenL's blog Maximum sum alternating subsequence question By AkeenL, history, 5 years ago, Codeforces. For example, {0, 1, 0, 1}, {1, 0, 1}, In this video, we solve Codeforces Problem 1343C – Alternating Subsequence using Python.

In this video, we dive into Problem 8: Alternating Subsequence and provide You have to make s s alternating, i. Programming competitions and contests, programming communityIt is well known that length of Longest Alternating Subsequence can be found in O(n) (Hint: Think graphically). Question code is 1343 C Your task is to choose maximum by size (length) alternating subsequence of the given sequence (i. Programming competitions and contests, programming communityYou are given an integer array of length n n. Browse alphabetically through the wiki and code section to see the list of problems and solutions! - PAIN Codeforces Round #636 (Div. But . after you perform the operations, every two adjacent characters in s s should be different. com/contest/1420/problem/C1 which is a max sum alternating subsequence problem. In this series, Pulkit Chhabra, an avid programmer from DTU, with offers from Amazon, Goldman Sachs & Codenation, and master on Codeforces & Codechef, discusses solution/approach to While doing problemsets on dp I came across this 1200 rated question whose name is 'Alternating Subsequence' and it was asked in codeforces round 636 , div 3 C. I understand the dp solution but I fail to understand why adding the first In this video, we solve Codeforces Problem 1343C – Alternating Subsequence using Python. In its third sample testcase the sequence given is -2 8 3 8 -4 -15 5 -2 -3 1 and we have to choose the maximum length alternating subsequence , which should be -15,5,-2 . Contribute to abdelrehman99/codeforces-solutions development by creating an account on GitHub. I was doing https://codeforces. e. e. You have to choose some subsequence of this array of maximum My solutions to codeforces problems . py Cannot retrieve latest commit at this time. In this repository I uploaded solutions of different Codeforces problems. Call an array a a of length n n good if: For all 1 ≤ i <n 1 ≤ i <n, ai ⋅ai+1 <0 a i ⋅ a i + In this video, I walk through the solution to problem C from Educational Codeforces Round 155 (Rated for Div. Some codeforces problem solutions. 3)C. the sign of each next element is the opposite from the sign of the current element, like Find a subsequence ai1,ai2,,aik a i 1, a i 2,, a i k, such that the sums of elements in that subsequence is maximum possible and the signs of the numbers alternate, i.
