Given a string and an integer K, create a new string by selecting the smallest character from the first K characters of the input string and repeating the process until the input string is empty.

• Iterate through the input string, selecting the smallest character from the first K characters each time.

• Remove the selected character from the input string and append it to the new string.

• Continue this process until the input string is empty.

• Return the final new string formed.

An operating system manages computer hardware and software resources and provides common services for computer programs.

• The OS manages memory, CPU, and input/output devices.

• It provides a user interface for interaction with the computer.

• It manages file systems and provides security features.

• Examples include Windows, macOS, and Linux.

• The OS kernel is the core component that interacts with hardware.

• The OS can be single-tasking or multi-tasking.

• Virtualization allows multiple OS i...read more

Array is a fixed-size data structure with elements stored sequentially, while linked list is a dynamic data structure with elements stored non-sequentially.

• Arrays have fixed size, while linked lists can grow dynamically.

• Accessing elements in an array is faster (O(1)), while in a linked list it is slower (O(n)).

• Inserting or deleting elements in an array can be inefficient, as it may require shifting elements, while in a linked list it is efficient.

• Example: Array - ['apple', 'b...read more

Code to find the factorial of a number

• Use a loop to multiply the number with all the numbers below it

• Handle the case when the number is 0 or 1 separately

• Use long data type to handle large factorials

There are 5 types of normalisation in database management.

• 1NF - Eliminate duplicate data

• 2NF - Eliminate partial dependencies

• 3NF - Eliminate transitive dependencies

• BCNF - Eliminate redundant data

• 4NF - Eliminate multi-valued dependencies

Normalization is the process of organizing data in a database to reduce redundancy and improve data integrity.

• Normalization involves breaking down a database into smaller, more manageable tables

• Each table should have a primary key and only contain data related to that key

• Normalization helps to prevent data inconsistencies and anomalies

• There are different levels of normalization, with each level building on the previous one

• Examples of normalization include converting repeating...read more

Implement a Stack using Queue by using two queues and maintaining the order of elements.

• Use two queues to simulate stack operations - push, pop, top.

• For push operation, add the element to the first queue.

• For pop operation, move all elements from the first queue to the second queue, except the last element which is popped.

• For top operation, return the last element in the first queue.

A computer is an electronic device that can perform various operations based on instructions given to it.

• Computers can process and store large amounts of data.

• They can perform complex calculations and execute programs.

• Examples include desktops, laptops, tablets, and smartphones.

Pointers in C are variables that store memory addresses. They are used to access and manipulate data directly in memory.

• Pointers are declared using an asterisk (*) before the variable name.

• Pointers can be used to pass variables by reference to functions.

• Dereferencing a pointer means accessing the value at the memory address it points to.

• Example: int *ptr; // declaring a pointer to an integer
