This project contains solutions for two problems along with their corresponding unit tests. The project structure is as follows:

pythonProject3/
│
├── problem1.py
├── problem2.py
├── run_tests.py
└── test/
    ├── test_problem1.py
    └── test_problem2.py

Given two strings source and target, return the minimum number of subsequences of source such that their concatenation equals target. If the task is impossible, return -1.

Examples:

• source = "abc", target = "abcbc", Output: 2
• source = "abc", target = "acdbc", Output: -1
• source = "xyz", target = "xzyxz", Output: 3

Given a list of strings containing parentheses, check if the parentheses are balanced. If there are unmatched left parentheses, mark them with x; if there are unmatched right parentheses, mark them with ?.

Example Input:

"bge)))))))))" 
"((IIII))))))" 
"()()()()(uuu" 
"))))UUUU((()" 

Example Output:

" ?????????" 
" ????" 
" x " 
"???? xx " 

• problem1.py - Contains the solution for Problem 1.
• problem2.py - Contains the solution for Problem 2.
• run_tests.py - Script to run all tests at once.
• test/test_problem1.py - Unit tests for Problem 1.
• test/test_problem2.py - Unit tests for Problem 2.

To run all tests, execute the following command in the project's root directory:

python run_tests.py
