Split a String in Balanced Strings
Balanced strings are those that have an equal quantity of 'L' and 'R' characters.
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:
Return the maximum number of balanced strings you can obtain.
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.
