Task 1: Monotonic Array

You are given an array of integers.

Write a script to find out if the given array is Monotonic. Print 1 if
it is otherwise 0.

An array is Monotonic if it is either monotone increasing or decreasing.

Monotone increasing: for i <= j , nums[i] <= nums[j]
Monotone decreasing: for i <= j , nums[i] >= nums[j]

Example 1

  Input: @nums = (1,2,2,3)
  Output: 1

Example 2

  Input: @nums = (1,3,2)
  Output: 0

Example 3

  Input: @nums = (6,5,5,4)
  Output: 1

MY NOTES: seems very easy. use reverse() in order not to detect
monotonically increasing and decreasing..

GUEST LANGUAGE: As a bonus, I also had a go at translating ch-1.pl
into C (look in the C directory for the translation)


Task 2: Reshape Matrix

You are given a matrix (m x n) and two integers (r) and (c).

Write a script to reshape the given matrix in form (r x c) with the
original value in the given matrix. If you can't reshape print 0.

Example 1

Input: $matrix = [ [ 1, 2 ], [ 3, 4 ] ]
       $r = 1
       $c = 4

Output: [ 1 2 3 4 ]

Example 2

Input: $matrix = [ [ 1, 2, 3 ] , [ 4, 5, 6 ] ]
       $r = 3
       $c = 2

Output: [ [ 1, 2 ], [ 3, 4 ], [ 5, 6 ] ]

Example 3

Input: $matrix = [ [ 1, 2 ] ]
       $r = 3
       $c = 2

Output: 0

MY NOTES: also quite easy, can be done if R1*C1==R2*C
(of course we have to discover R1 and C1, the dimensions o
the original matrix).  Also have to read the matrix in..

GUEST LANGUAGE: As a bonus, I also had a go at translating ch-2.pl
into C (look in the C directory for the translation).  Needed to
pass original sizes into C routine..
