Create a function called encrypt that accepts a string as input, & returns the encrypted string & the key as outputs.

The encryption algorithm is as follows:

- Generate a random integer between 1-127. This is the key (e.g. key= 10)

- Shift the ASCII code value of all characters in the string by an amount equal to the key plus the

index # of the character in the string (so the code of the 1st char in the string will be shifted by key + 1,

the second by key + 2, and so on).

- Before converting the code values back to char, use a -modulo arithmetic approach to ensure that all the

adjusted values are in the ASCII code range (1 to 127)if the new ASCII value is >=127, -127 to get the new value.

(Note: a standard clock is a modulo-12 device w respect to hrs.) The built-in mod func may be used to accomplish this.
