Assistant System Engineer

You have been given an array/list 'ARR' of integers. Your task is to find the second largest element present in the 'ARR'.

Note:

a) Duplicate elements may be present.

b) If no such element is present return -1.

Example:

Input: Given a sequence of five numbers 2, 4, 5, 6, 8.

Output:  6

Explanation:
In the given sequence of numbers, number 8 is the largest element, followed by number 6 which is the second-largest element. Hence we return number 6 which is the second-largest element in the sequence.

A robot on an infinite XY-plane starts at point (0, 0) and faces north. The robot can receive one of three possible types of commands (given in the COMMANDS array/list):

1) -2: turn left 90 degrees,

2) -1: turn right 90 degrees, or

3) 1 <= ‘K’ <= 9: move forward K units.

Some of the grid squares are obstacles. The ‘ith’ obstacle is at grid point OBSTACLES[i] = (Xi, Yi).

If the robot would try to move onto them, the robot stays on the previous grid square instead (but still continues following the rest of the route.)

Return the maximum Euclidean distance that the robot will be from the origin squared (i.e. if the distance is 5, return 25).

Note :

North means +Y direction.
East means +X direction.
South means -Y direction.
West means -X direction.

For example:

N = 1, M = 0 
COMMANDS = [3], OBSTACLES = []

The final answer would be 9 since it moves 3 steps north.

Given an array with N elements, the task is to reverse all the array elements and print the reversed array.

Given an integer ‘N’, you are supposed to return the factorial of the given integer in the form of a string.
