1. Rat In A Maze

Asked in companies
You are given a starting position for a rat which is stuck in a maze at an initial point (0, 0) (the maze can be thought of as a 2-dimensional plane). The maze would be given in the form of a square matrix of order 'N' * 'N' where the cells with value 0 represent the maze’s blocked locations while value 1 is the open/available path that the rat can take to reach its destination. The rat's destination is at ('N' - 1, 'N' - 1). Your task is to find all the possible paths that the rat can take to reach from source to destination in the maze. The possible directions that it can take to move in the maze are 'U'(up) i.e. (x, y - 1) , 'D'(down) i.e. (x, y + 1) , 'L' (left) i.e. (x - 1, y), 'R' (right) i.e. (x + 1, y).
Note:
Here, sorted paths mean that the expected output should be in alphabetical order.
For Example:
Given a square matrix of size 4*4 (i.e. here 'N' = 4):
1 0 0 0
1 1 0 0
1 1 0 0
0 1 1 1
Expected Output:
DDRDRR DRDDRR
i.e. Path-1: DDRDRR and Path-2: DRDDRR
The rat can reach the destination at (3, 3) from (0, 0) by two paths, i.e. DRDDRR and DDRDRR when printed in sorted order, we get DDRDRR DRDDRR.
2. Ways to express ‘n’ as the sum of consecutive numbers
Hard

Asked in companies
You are given the number ‘N’. The task is to find the number of ways to represent ‘N’ as a sum of two or more consecutive natural numbers.
Example:
N = 9
‘9’ can be represented as:
2 + 3 + 4 = 9
4 + 5 = 9
The number of ways to represent ‘9’ as a sum of consecutive natural numbers is ‘2’. So, the answer is ‘2’.
Note:
1. The numbers used to represent ‘N’ should be natural numbers (Integers greater than equal to 1).
