Given 2 [run-length encoded](https://en.wikipedia.org/wiki/Run-length_encoding) strings `s` and `t`. Determine if they represent the same string.\n\n**Example 1:**\n```\nInput: s = "3a1b", t = "2a1a1b"\nOuptut: true\n```\n\n**Example 2:**\n```\nInput: s = "3a1b3c", t = "2a1a1b2c1d"\nOuptut: false\n```\n\nExpected `O(1)` space solution.\n\n**Follow-up:**\nGiven a RLE string `s` and a `width` of a board. Assume that the board is filled from **left to right** such that each line has exactly `width` chars. Output the RLE string that represents the board rows from **right to left** without constructing the board.\n\n**Example:**\n```\nInput: s = "3a1b3c3d2a", width = 4\n\naaab\ncccd\nddaa\n\nOutput: "1b3a1d3c2a2d"\n```
