Function getColumn

Function getColumnThe function/method getColumn accepts four arguments – R, C, matrix and K. The integer R represents the number of rows in the matrix, the integer C represents the number of columns in the matrix, a two dimensional array of integers matrix and the integer K represents the position of a column in the matrix.

The function/method getColumn must return an array of integers containing all the integers in the K^th column of the given matrix.

Your task is to implement the function getColumn so that it passes all the test cases.

The following structure is used to represent the boundedArray and is already defined in the default code (Do not write this definition again in your code).

typedef struct BoundedArray
{
    int SIZE;
    int *arr;
} boundedArray;

IMPORTANT: Do not write the main() function as it is already defined.

Example Input/Output 1:
Input:
5 4
98 62 65 28
37 47 14 89
19 66 48 43
84 16 75 35
62 88 77 94
3

Output:
Column 3: 65 14 48 75 77

Explanation:
Here K = 3, the integers in the 3^rd column are 65, 14, 48, 75 and 77.
Hence the output is
Column 3: 65 14 48 75 77

Example Input/Output 2:
Input:
4 7
87 51 76 54 16 32 63
51 86 57 48 91 32 93
44 32 69 22 38 49 94
63 40 23 70 88 13 87
2

Output:
Column 2: 51 86 32 40
