1221. Split a String in Balanced Strings

Level - easy

Task

Balanced strings are those that have an equal quantity of 'L' and 'R' characters.

Given a balanced string s, split it into some number of substrings such that:

Each substring is balanced. Return the maximum number of balanced strings you can obtain.

Объяснение

Дана строка s, состоящая только из символов 'L' и 'R'. Строка считается сбалансированной, если количество символов 'L' равно количеству символов 'R' в этой строке. Необходимо разделить строку s на максимально возможное количество сбалансированных подстрок. Вернуть количество таких подстрок.

Например:

  • Ввод: s = "RLRRLLRLRL"
  • Вывод: 4
  • Объяснение: Строка может быть разделена на 4 подстроки: "RL", "RRLL", "RL", "RL". Каждая из этих подстрок сбалансирована.

Example 1:

Input: s = "RLRRLLRLRL"
Output: 4
Explanation: s can be split into "RL", "RRLL", "RL", "RL", each substring contains same number of 'L' and 'R'.

Example 2:

Input: s = "RLRRRLLRLL"
Output: 2
Explanation: s can be split into "RL", "RRRLLRLL", each substring contains same number of 'L' and 'R'.
Note that s cannot be split into "RL", "RR", "RL", "LR", "LL", because the 2nd and 5th substrings are not balanced.

Example 3:

Input: s = "LLLLRRRR"
Output: 1
Explanation: s can be split into "LLLLRRRR".

Constraints:

  • 2 <= s.length <= 1000
  • s[i] is either 'L' or 'R'.
  • s is a balanced string.
