Leetcode C++ tempate

This is template for leetcode.com problems solving with VSCode. It is based on cmake compiler, clang-format and ctest.

How to install:

sudo apt install cmake clang-format

How to use:

Solve your leetcode problems in solution.cpp:

// 389. Find the Difference
// https://leetcode.com/problems/find-the-difference

class Solution {
    public:
        char findTheDifference(std::string s, std::string t) {
            ...
        }
    }

Write required test tempate during solution development in test.cpp:

#include "solution.cpp"
int main(int n, char **args) {
    string s = args[1];
    string t = args[2];
    string d = args[3];
    char expected = d[0];
    Solution sol;
    char result = sol.findTheDifference(s, t);
    if (result == expected) {
        return 0;
    } else {
        return 1;
    }
}

Actual tests and their parameters are specified in CMakeLists.txt like this:

add_test(
    NAME Test_0
    COMMAND "$<TARGET_FILE:cpp_test>" "abc" "abcd" "d"
)

add_test(
    NAME Test_1
    COMMAND "$<TARGET_FILE:cpp_test>" "" "a" "a"
)

add_test(
    NAME Test_2
    COMMAND "$<TARGET_FILE:cpp_test>" "asd" "dtsa" "t"
)

Run your test to check your solution before submit with CTest from VSCode or manually:

user@host:~/leetcode$ cd ./build/
user@host:~/leetcode/build$ ctest
    Test project /home/user/projects/cpp/leetcode/build
        Start 1: Test_0
    1/3 Test #1: Test_0 ...........................   Passed    0.00 sec
        Start 2: Test_1
    2/3 Test #2: Test_1 ...........................   Passed    0.00 sec
        Start 3: Test_2
    3/3 Test #3: Test_2 ...........................***Failed    0.00 sec
    
    67% tests passed, 1 tests failed out of 3
    
    Total Test time (real) =   0.00 sec
    
    The following tests FAILED:
