Using Python: A Mezza Pinta sequence is a series of values starting with zero, then alternatively subtracting and adding subsequent integers, which increment by a Mezza Pinta Step. If the Mezza Pinta Step was 1, the values in this sequence would be 0, +1, -2, +3, -4, +5, -6. and when these values are summed, they produce the sequence: 0, 1, -1, 2, -2, 3, -3. In this case, the 5th index is 3. The values with a Mezza Pinta Step of 3 would be: 0, 3, -6, 9, -12, 15 and would produce the sequence: 0, 3, -3, 6, -6, 9. The 2nd index is -3 and the 4th index is -6. (keep in mind that the index of a Mezza Pinta series always starts with zero): Write a function named q4() that accepts two (2) integers from the user a Mezza Pinta Step and n. Your program should then calculates the nth index in the sequence.

Output should read exactly as below:

This program determines the nth index of a Mezza Pinta Sequence Enter the Mezza Pinta step: 5 Enter the value for : 14 The 14th index with Mezza Pinta Step 5 is 35
