You are given a word like `hellloooo` print all the repeating character index and the number of time it is has been repeated: https://leetcode.com/problems/positions-of-large-groups\n\n**Example 1:**\n```\nInput: "hellloooo"\nOutput: [[2, 3], [5, 4]]\nExplanation: hellloooo has l and o as repeating characters so return index of l which is at 2\nand the number of times it has been repeated is 3. Same goes for O.\n```\n\n**Example 2:**\n```\nInput: "leetcodeee"\nOutput: [[1, 2], [7, 3]]\n```\n\n**Follow-up:**\nWhat if you need to print the repeated character as well?\n\n**Example 1:**\n```\nInput: "hellloooo"\nOutput : [[\'l\', 3], [\'o\', 4]]\n```\n\n**Example 2:**\n```\nInput: "leetcodeee"\nOutput: [[\'e\', 5]]\n```\n\n```\npublic List<List<Integer, Integer>> findRepeated(String s) {\n}\n```
