Reversing a string in Python can be done using slicing, loops, or built-in functions.
Using slicing: reversed_string = original_string[::-1]
Using the reversed() function: reversed_string = ''.join(reversed(original_string))
Using a loop: reversed_string = ''.join([original_string[i] for i in range(len(original_string)-1, -1, -1)])
The Fibonacci series is a sequence where each number is the sum of the two preceding ones, starting from 0 and 1.
The series starts with 0 and 1: 0, 1, 1, 2, 3, 5, 8, 13, ...
The nth Fibonacci number can be calculated using recursion or iteration.
A common iterative approach uses a loop to calculate Fibonacci numbers.
Example of the first 10 Fibonacci numbers: [0, 1, 1, 2, 3, 5, 8, 13, 21, 34].
The Fibonacci sequence h...
To verify an IP range, check if the given IP falls within the specified range.
Check if the given IP is greater than or equal to the start IP of the range
Check if the given IP is less than or equal to the end IP of the range
If both conditions are true, then the IP falls within the range
Loop in a linked list occurs when a node points to a previous node, creating a cycle.
A loop in a linked list can be detected using Floyd's cycle detection algorithm.
To detect a loop, use two pointers - one moving at twice the speed of the other.
If the two pointers meet at some point, then there is a loop in the linked list.

I applied via Recruitment Consulltant and was interviewed in May 2022. There were 2 interview rounds.
The question was related to make a code on a function which takes a pneumonic string as input and gives a sorted list of ascending numbers as output. The twist was that the input can contain anything like int, float comp, characters, alphabets, etc ;you name it, it can contain anything.
