The question asks to find the similarity between two words by developing our own sense of similarity.

• Normalize the length of the Longest Common Subsequence (LCS) by dividing it by the total length of the string.

• Use a breadth-first search (BFS) algorithm to traverse the binary tree level by level.

• Create a doubly linked list for each level and append the nodes to it.

• Connect the doubly linked lists of each level to form the final result.

Explaining Spring concepts: Qualifier, Autowired, Bean scope, and Dependency management

• Qualifier is used to specify which bean to inject when multiple beans of the same type are present

• Autowired automatically injects a bean by type, but can also use Qualifier to specify which bean to inject

• Bean scope determines the lifecycle of a bean, such as singleton or prototype

• Dependency management ensures that all required depend
