You are given two strings s and sub. You are also given a 2D character array mappings where mappings[i] = [oldi, newi] indicates that you may perform the following operation any number of times:
oldi of sub with newi.Each character in sub cannot be replaced more than once.
Return true if it is possible to make sub a substring of s by replacing zero or more characters according to mappings. Otherwise, return false.
A substring is a contiguous non-empty sequence of characters within a string.

Example 1:
\n\n\nInput: s = "fool3e7bar", sub = "leet", mappings = [["e","3"],["t","7"],["t","8"]]\nOutput: true\nExplanation: Replace the first 'e' in sub with '3' and 't' in sub with '7'.\nNow sub = "l3e7" is a substring of s, so we return true.\n\n
Example 2:
\n\n\nInput: s = "fooleetbar", sub = "f00l", mappings = [["o","0"]]\nOutput: false\nExplanation: The string "f00l" is not a substring of s and no replacements can be made.\nNote that we cannot replace '0' with 'o'.\n\n\n
Example 3:
\n\n\nInput: s = "Fool33tbaR", sub = "leetd", mappings = [["e","3"],["t","7"],["t","8"],["d","b"],["p","b"]]\nOutput: true\nExplanation: Replace the first and second 'e' in sub with '3' and 'd' in sub with 'b'.\nNow sub = "l33tb" is a substring of s, so we return true.\n\n\n\n
