The cipher will use the key to determine the direction of the shift, with a ‘u’ indicating that the character must be shifted upwards while a ‘d’ indicating a downward shift. The number of characters in the key will determine the number of positions to shift. The given text variable will only contain characters from the ASCII table with values between 32 and 126. If the key is invalid (empty string, contains characters other than u and d) or the text is invalid (empty string), no encryption occurs and the function returns the original text. If the text has more characters than the key, the key will loop through again to accommodate the additional text characters. An iterative approach should be used to solve this problem. Brute force…

- 01. Given a string s containing only three types of characters: '(', ')' and '*', return true if s is valid. The following rules define a valid string: Any left parenthesis '(' must have a corresponding right parenthesis ')'. Any right parenthesis ')' must have a corresponding left parenthesis '('. Left parenthesis '(' must go before the corresponding right parenthesis ')'. '*' could be treated as a single right parenthesis ')' or a single left parenthesis '(' or an empty string "". Example 1: Input: s = "()" Output: true.Which of the following two sets are disjoint? Select one: a.
