P6832 [Cnoi2020] Subchord
Description
Cirno has a string $\texttt{S}$, and wants you to find the maximum number of occurrences among all non-empty substrings of $\texttt{S}$. Denote this number as $p$.
Input Format
One line, a string $\texttt{S}$.
Output Format
One line, an integer $p$.
Explanation/Hint
### Constraints and Notes
For $100\%$ of the testdata, it is guaranteed that: $0 < |\texttt{S}| \le 10^7$, and $\texttt{S}_x \in [\texttt{a},\texttt{z}]$.
#### Subtasks (this problem uses bundled tests)
- Subtask 1 ($40\%$): $|\texttt{S}| \le 100$.
- Subtask 2 ($40\%$): $|\texttt{S}| \le 10^5$.
- Subtask 3 ($20\%$): no special constraints.
### Glossary
- **Substring**: A subsequence consisting of any number of consecutive characters in a string is called a substring of that string.
