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 replace any number of oldi characters 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
