Clone a linked list with random pointers.
Create a new node for each node in the original list.
Store the mapping between the original and cloned nodes in a hash table.
Traverse the original list again and set the random pointers in the cloned list using the hash table.
Return the head of the cloned list.
The angle between minute and hour hand for a particular time can be calculated using a formula.
The formula is: |(30*H) - (11/2)*M| degrees
Where H is the hour hand position and M is the minute hand position
If the result is greater than 180 degrees, subtract it from 360 degrees to get the acute angle
For example, at 3:15, H=3 and M=15, so the angle is |(30*3) - (11/2)*15| = 7.5 degrees
The default = operator and copy constructor are used to assign values and create copies of objects.
The default = operator is used to assign the values of one object to another object of the same class.
The copy constructor is used to create a new object by copying the values of an existing object.
Explicitly defining these functions is necessary when the default behavior is not sufficient or when the class contains ...
Yes, the destructor will work for obj2.
The destructor is a special member function that is automatically called when an object is destroyed.
When obj2 is assigned the value of obj1, it will still have its own destructor that will be called when obj2 is destroyed.
The destructor is responsible for cleaning up any resources allocated by the object, regardless of how the object was assigned or copied.
The garbage collector cannot work explicitly when objects have explicit references.
Garbage collector cannot collect objects that have explicit references.
Explicit references can be created using pointers or strong references.
If an object is explicitly referenced, it will not be considered garbage by the collector.
Examples of explicit references include global variables or objects referenced by other active objects...
Operator overloading allows the same operator to be used for different purposes based on the operands.
Operator overloading provides a way to make operators work with user-defined types.
It allows us to define the behavior of an operator when applied to objects of a class.
It can simplify code and make it more readable by allowing intuitive use of operators.
Examples include overloading the '+' operator to concatenate...
