Programmer Analyst Trainee

You are given a 'M' x 'N' matrix of characters, 'CHARACTER_MATRIX' and a string 'WORD'. Your task is to find and print all occurrences of the string in the given character matrix. You are allowed to search the string in all eight possible directions, i.e. North, South, East, West, North-East, North-West, South-East, South-West.

Note: There should not be any cycle in the output path. The entire string must lie inside the matrix boundary. You should not jump across boundaries, i.e. from row 'N' - 1 to 0 or column 'N' - 1 to 0 or vice versa.

Example:

Consider below matrix of characters,
[ 'D', 'E', 'X', 'X', 'X' ]
[ 'X', 'O', 'E', 'X', 'E' ] 
[ 'D', 'D', 'C', 'O', 'D' ]
[ 'E', 'X', 'E', 'D', 'X' ]
[ 'C', 'X', 'X', 'E', 'X' ]

If the given string is "CODE", below are all its occurrences in the matrix:

'C'(2, 2) 'O'(1, 1) 'D'(0, 0) 'E'(0, 1)
'C'(2, 2) 'O'(1, 1) 'D'(2, 0) 'E'(3, 0)
'C'(2, 2) 'O'(1, 1) 'D'(2, 1) 'E'(1, 2)
'C'(2, 2) 'O'(1, 1) 'D'(2, 1) 'E'(3, 0)
'C'(2, 2) 'O'(1, 1) 'D'(2, 1) 'E'(3, 2)
'C'(2, 2) 'O'(2, 3) 'D'(2, 4) 'E'(1, 4)
'C'(2, 2) 'O'(2, 3) 'D'(3, 3) 'E'(3, 2)
'C'(2, 2) 'O'(2, 3) 'D'(3, 3) 'E'(4, 3)

You are given an array of N elements. This array represents the digits of a number. In an operation, you can swap the value at any two indices. Your task is to find the maximum number by using operation at most once.

For Example :

Input array [1,3,2,7] so basically this array represents the number 1327.
All the possible combinations are :
1. [3 1 2 7] get by swapping indices 1 and 2.
2. [2 3 1 7] get by swapping indices 1 and 3.
3. [7 3 2 1] get by swapping indices 1 and 4.
4. [1 2 3 7] get by swapping indices  2 and 3.
5. [1 7 2 3] get by swapping indices 2 and 4.
6. [1 3 7 2] get by swapping indices 3 and 4.
Out of all the possible combinations, 3 give the maximum number as 7321, so we will return [7 3 2 1].

Note :

The input may have 0 before the most significant digit. e.g. [0,3,5,7] is a valid input and this represents number 357.

Question was to find the day after 45 days if today is Monday.

She first asked to introduce myself and then she just simply asked what location i wanted. And that was it
