Write a Python program that splits, doubles, and reverse each input string entered. For each string, split it at the given integer, and then output it in format as shown below. Convert all stings entered to uppercase for output. Assume string length is greater than the split value. Refer to the sample output below. Sample Runs: Enter a string: holiday Enter the number to split on: 3 HOL-YADI-LOH-IDAY Enter a string: TATTARRATTAT Enter the number to split on: 6 TATTAR-TATTAR-RATTAT-RATTAT...

Define a Q-sequence recursively as follows. B.   x, 4 − x is a Q-sequence for any real number x. R.   If x1, x2,   , xj and y1, y2,   , yk are Q-sequences, so is     x1 − 1, x2,   , xj, y1, y2,   , yk − 3. Use structural induction (i.e., induction on the recursive definition) to prove that the sum of the numbers in any Q-sequence is 4. Base Case: Any Q-sequence formed by the base case of the definition has sum x +...
