Binary search is a divide and conquer algorithm that efficiently finds the target value in a sorted array.

• Binary search compares the target value to the middle element of the array and eliminates half of the remaining elements based on the comparison.

• If the target value is less than the middle element, the search continues on the left subarray. If it is greater, the search continues on the right subarray.

• This process is repeated until the target value is found or the subarray...read more

Polymorphism is the ability of an object to take on many forms. It allows objects of different classes to be treated as the same type.
