Given a string. The task is to find the maximum number P, such that given string can be partitioned into P contiguous substrings such that any two adjacent substring must be different. More formally and .
Input: str = “aabccd”
We can divide the given string into four string, like “a”, “ab”, “c”, “cd”. We can not divide
it more than four parts, if we do then the condition will not
Input: str = “aaaa”
- Here we only have to focus on the value of P, not upon finding those P substrings.
- We will solve it greedily, we always check the current string that we have with the previous string that has been taken already.
- If we found that both of them are same then we will go forward otherwise create a partition here and change the previous track of the string to current string, means we will treat this current string as the previous string for future comparison.
Below is the implementation of above Approach:
Time Complexity: O(N), where N is the length of the string.
