BASIC PROGRAMMING QUESTIONS IN CPP
Program to calculate sum of series, manipulate string, and manipulate employees' table
For calculating sum of series, use a loop to iterate through the given series and add each element to a running total
For manipulating a string, use string manipulation functions like substring, replace, or concatenate to modify the given string
For manipulating an employees' table in SQL, use SQL queries like UPDATE, INSERT, or DELETE ...

Hashing is a technique used to map data to a fixed-size array, collision occurs when two different inputs produce the same hash value.
Hashing involves using a hash function to map data to a fixed-size array.
Collision happens when two different inputs produce the same hash value.
Common techniques to handle collisions include chaining and open addressing.
No, time complexity of HashMap is not always O(1).
Time complexity of HashMap is O(1) on average, but can degrade to O(n) in worst case scenarios.
Worst case scenarios include hash collisions, which can lead to linear probing and degrade performance.
Load factor and capacity of the HashMap can also affect time complexity.
In scenarios where many keys hash to the same index, the time complexity can degrade.

gcd stands for greatest common divisor, the largest positive integer that divides two or more numbers without leaving a remainder.
gcd is used to find the largest integer that can evenly divide two or more numbers.
It is commonly used in mathematics and computer science algorithms.
For example, the gcd of 12 and 18 is 6, as 6 is the largest number that can divide both 12 and 18 without leaving a remainder.
ARC stands for Automatic Reference Counting, a memory management technique used in programming languages like Objective-C and Swift.
ARC automatically tracks and manages the memory used by objects in a program
It increases the retain count of an object when it is referenced and decreases it when it is no longer needed
ARC helps prevent memory leaks and retain cycles in iOS and macOS development
