passing custom function in sort cpp

To pass a custom function in C++'s sort function, you can use a lambda function or a function pointer. Here are the steps to do so:

1. Define the custom function that you want to pass to the sort function. This function should take two arguments of the same type as the elements in the container being sorted, and it should return a bool value indicating the sorting order.

2. Pass the custom function as an argument to the sort function. You can do this by using a lambda function or a function pointer.

3. Lambda function: You can define an inline lambda function directly as an argument to the sort function. The lambda function should have the same signature as the custom function. For example:

   cpp sort(container.begin(), container.end(), [](type1 arg1, type2 arg2) { // custom sorting logic return true; // or false });

4. Function pointer: If you have a separate function defined, you can pass its name as an argument to the sort function. Make sure that the function has the same signature as the custom function. For example:

   ```cpp bool customSort(type1 arg1, type2 arg2) { // custom sorting logic return true; // or false }

   sort(container.begin(), container.end(), customSort); ```

5. The sort function will use the custom function to compare elements in the container and sort them accordingly. The custom function will be called multiple times by the sort function as it rearranges the elements.

That's it! By following these steps, you can pass a custom function to the sort function in C++.
