Explanation...read more
Ans. 
Find the sum of the subarray with the maximum sum among all subarrays in a given array.
• Iterate through the array and keep track of the current sum and maximum sum seen so far.

• If the current sum becomes negative, reset it to 0 as it won't contribute to the maximum sum.

• Return the maximum sum as the result.

• Example: For input arr = [-2, 1, -3, 4, -1], the maximum subarray sum is 4.

Q2. What ia polymorphism Pointers etc.
Ans. 
Polymorphism is the ability of a function or method to behave differently based on the object it is called with.
• Polymorphism allows objects of different classes to be treated as objects of a common superclass.

• There are two types of polymorphism: compile-time (method overloading) and runtime (method overriding).

• Example: Animal class with methods eat() and sleep(). Dog and Cat classes can inherit from Animal and override
