- Ans.
A thread pool is a group of threads that can be reused to execute multiple tasks concurrently.
Define a task interface that encapsulates the work to be done

- Q4. Shared and unique ptr implementation

- Q5. Given the frequency of three letters 'a' 'b' and 'c'..form the largest string by using a,b, and c provided 3 (a , b or c )cant be together and the possible string should be largest.
- Ans.
Form the largest string using a, b, and c with the condition that 3 (a, b, or c) can't be together.
Start with the most frequent letter and alternate with the other two.
If there are two letters with the same frequency, start with the one that has the least number of adjacent letters.
Example: 'abcabcab' is not valid, but 'abacbac' is valid and larger.

- Ans.
Code to find strings in a dictionary matching a given pattern

- Q1. Sort an unsorted array without inbuilt methods
- Ans.
Implement a sorting algorithm to sort an unsorted array of strings without using inbuilt methods.
Use a sorting algorithm like bubble sort, selection sort, or insertion sort to manually sort the array.
Compare each element with the next one and swap them if they are in the wrong order.
Repeat this process until the array is sorted.
Example: ['banana', 'apple', 'cherry'] -> ['apple', 'banana', 'cherry']
