Three questions regarding dynamic programming and arrays
Largest Common Subsequence DP problem involves finding the longest subsequence that is common to two given strings.
Use dynamic programming to solve this problem efficiently.
Create a 2D array to store the lengths of common subsequences of substrings.
Traverse the array to find the length of the largest common subsequence.
Example: Given strings 'ABCD' and 'ACD', the largest common subsequence is 'ACD'.
Check if a string contains any palindromes
Iterate through each string in the array
Reverse the string and compare it with the original string to check for palindrome
Return true if any palindrome is found, false otherwise
SQL is a traditional relational database management system, while NoSQL is a non-relational database system.
SQL is structured, uses tables with rows and columns, and follows ACID properties.
NoSQL is unstructured, uses collections of documents, key-value pairs, or graphs, and is horizontally scalable.
SQL is better for complex queries and transactions, while NoSQL is better for large amounts of data and flexible schemas.

DaemonSet ensures that all or some nodes run a copy of a Pod
DaemonSet is a Kubernetes resource that ensures a copy of a Pod is running on all or some nodes in a cluster
It is useful for running a single instance of a Pod on every node in a cluster
DaemonSet is commonly used for monitoring, logging, and other system-level services
Example: Running a logging agent on every node in a Kubernetes cluster
Deployment is a way to manage and update applications in Kubernetes. StatefulSet is used for stateful applications with unique identities.
Deployment is used for stateless applications, while StatefulSet is used for stateful applications.
Deployment manages replica sets and ensures a desired state is maintained.
