Python3 : Write the function longestRun(s, chars) that takes a possibly-empty string s and a second possibly-empty string of chars. We will say that a character is "good" if it is in the chars string (case insensitively, so "A" and "a" would match). The function should return the length of the longest consecutive run of good characters in the given string s. For example, consider: longestRun("abbcazBbcababb","bz"). This returns 3 (look for "zBb"). Restrictions: for loop, slicing cannot be used, if...

Add or Subtract. Write a function (add-sub-string s). The function consumes a Str of even length, where every even- numbered character is either "+" or "-", and odd-valued characters are numeric The function should add up all the digits that follow a "+", and subtract all the digits that follow a "-". For example, (add-sub-string "+3+4-5") => 2 (add-sub-string "-5+3+4-6-6") - 10 => The interface file contains the function char->nat that converts a numeric Char to the corresponding numeric value....
