JVM garbage collection is a process of automatically managing memory in Java programs by reclaiming unused memory.
Garbage collection is the process of identifying and deleting objects in memory that are no longer needed.
JVM uses different algorithms like Mark-Sweep, Mark-Compact, and Copying to perform garbage collection.
Examples of garbage collection in Java include the use of 'System.gc()' method to suggest garb...
Yes, React uses one-way data binding to ensure that changes in the UI trigger updates in the underlying data model.
React uses a unidirectional data flow, where data flows from parent components to child components.
Changes in the UI trigger updates in the underlying data model, but not the other way around.
This helps in maintaining a predictable state of the application and improves performance.
Example: When a user...

Time complexity refers to the amount of time an algorithm takes to run as a function of the input size.
Time complexity is typically expressed using Big O notation, which describes the worst-case scenario.
Common time complexities include O(1) for constant time, O(log n) for logarithmic time, O(n) for linear time, O(n^2) for quadratic time, and O(2^n) for exponential time.
For example, searching for an element in a s...
Print all permutations of a string iteratively and recursively.
Iterative approach: Use a stack to keep track of characters and their positions. Swap characters to generate permutations.
Recursive approach: Use backtracking to generate all possible permutations by swapping characters.
Example: Input 'abc', output ['abc', 'bac', 'cab', 'acb', 'bca', 'cba']

- Q1. Explain difference between numpy array and list
- Ans.
Numpy arrays are more efficient for numerical operations compared to lists.
Numpy arrays are homogeneous in nature, while lists can contain different data types.
Numpy arrays support vectorized operations, making them faster for numerical computations.
Numpy arrays require less memory compared to lists for large datasets.
Example: np_array = np.array([1, 2, 3]) vs list = [1, 2, 3]
