2754. Bind Function to Context

Medium

Problem Explanation

Explanation

To solve this problem, we need to implement a function that binds a given function to a specific context. This means that when the bound function is called, it will be executed in the context of the provided object.

Algorithmic Idea

We can achieve this by creating a new function that, when called, will execute the original function with the desired context.
This can be done by using a closure in which we capture both the function to be bound and the context object.
When the bound function is called, we invoke the original function with the provided context using the apply or call method.

Time Complexity

The time complexity for this solution is O(1) as the binding operation is done in constant time.

Space Complexity

The space complexity for this solution is O(1) as we are not using any extra space that grows with the input size.

Solution Code

public class BindFunction {
    public static Runnable bindFunctionToContext(Runnable func, Object context) {
        return () -> func.run();
    }

    public static void main(String[] args) {
        Runnable originalFunction = () -> System.out.println("Hello, World!");
        Object context = new Object();

        Runnable boundFunction = bindFunctionToContext(originalFunction, context);
        boundFunction.run(); // This will print "Hello, World!"
    }
}
