The lottery program involves generating random numbers, comparing digits, and using Boolean operators. Suppose you want to develop a program to play lottery. The program randomly generates a lottery of a two-digit number, prompts the user to enter a two-digit number, and determines whether the user wins according to the following rules:

1. If the user input matches the lottery number in the exact order, the award is $10,000.

2. If all digits in the user input match all digits in the lottery number, the award is $3,000.

3. If one digit in the user input matches a digit in the lottery number, the award is $1,000. Note that the digits of a two-digit number may be 0.

If a number is less than 10, we assume the number is preceded by a 0 to form a two-digit number. For example, number 8 is treated as 08 and number 0 is treated as 00 in the program.

Output: Test Cases

Case-1 Enter your lottery pick (two digits): 15 The lottery number is 15 Exact match: you win $10,000

Case-2 Enter your lottery pick (two digits): 45 The lottery number is 54 Match all digits: you win $3,000

Case-3 Enter your lottery pick: 23 The lottery number is 34 Match one digit: you win $1,000

Case-4 Enter your lottery pick: 23 The lottery number is 14 Sorry: no match
