VLOOKUP searches for a value in the first column of a table and returns a corresponding value in the same row. INDEX/MATCH uses two functions to look up a value based on its position in a table.

• VLOOKUP only searches for values in the first column of a table, while INDEX/MATCH can search for values in any column.

• INDEX/MATCH is more flexible and efficient for large datasets.

• VLOOKUP is easier to use for simple lookups with small datasets.

• INDEX/MATCH can handle errors more effect...read more

Design an employee-Manager class and write a method to display employee organizational hierarchy.

• Create an Employee class with attributes like name, id, managerId, etc.

• Create a Manager class that inherits from Employee class and has a list of employees under them.

• Write a method to display the hierarchy using recursion.

• Use a data structure like a dictionary to store the employees and their managers.

• Consider edge cases like circular references and missing managers.

Phases of clinical trials are stages of drug development that determine safety and efficacy.

• Phase 1: Small group of healthy volunteers to determine safety and dosage

• Phase 2: Larger group of patients to determine efficacy and side effects

• Phase 3: Even larger group of patients to confirm efficacy, monitor side effects, and compare to existing treatments

• Phase 4: Post-marketing surveillance to monitor long-term effects and safety in larger population

Find pairs from array whose sum is equal to target.

• Use a hashmap to store the difference between target and each element in the array.

• Iterate through the array and check if the current element exists in the hashmap.

• If it exists, then a pair with the sum equal to target is found.
