Good Key, Bad Key solution codeforces

There are 𝑛n chests. The 𝑖i-th chest contains 𝑎𝑖ai coins. You need to open all 𝑛n chests in order from chest 11 to chest 𝑛n. Good Key, Bad Key solution codeforces There are two types of keys you can use to open a chest: The first line contains an integer 𝑡t (1≤𝑡≤10001≤t≤1000) — the number of test cases. The first line of each test case contains an integer 𝑛n (2≤𝑛≤2⋅1052≤n≤2⋅105) — the … Read more

[Coding] Double Strings solution codeforces

[Coding] Double Strings solution codeforces You are given 𝑛n strings 𝑠1,𝑠2,…,𝑠𝑛s1,s2,…,sn of length at most 88. For each string 𝑠𝑖si, determine if there exist two strings 𝑠𝑗sj and 𝑠𝑘sk such that 𝑠𝑖=𝑠𝑗+𝑠𝑘si=sj+sk. That is, 𝑠𝑖si is the concatenation of 𝑠𝑗sj and 𝑠𝑘sk. Note that 𝑗j can be equal to 𝑘k. Recall that the concatenation of strings 𝑠s and 𝑡t is 𝑠+𝑡=𝑠1𝑠2…𝑠𝑝𝑡1𝑡2…𝑡𝑞s+t=s1s2…spt1t2…tq, where 𝑝p and 𝑞q are the lengths of strings 𝑠s and 𝑡t respectively. For example, concatenation of “code” and “forces” is “codeforces“. Input The first line contains … Read more

Cypher solution codeforces- Luca has a cypher made up of a sequence of 𝑛n wheels, each with a digit 𝑎𝑖ai written on it. On the 𝑖i-th wheel, he made 𝑏𝑖bi moves. Each move is one of two types: up move (denoted by 𝚄U): it increases the 𝑖i-th digit by 11. After applying the up move on 99, it becomes 00. down move (denoted by 𝙳D): it decreases the 𝑖i-th digit by 11. … Read more
