Wave Print Row Wise [codingblocks]

Take as input a two-d array. Wave print it row-wise.

Input Format
Two integers M(row) and N(column) and further M * N integers(2-d array numbers).

Constraints
Both M and N are between 1 to 10.

Output Format
All M * N integers are seperated by commas with 'END' written in the end(as shown in example).

Sample Input
4 4
11 12 13 14
21 22 23 24
31 32 33 34
41 42 43 44

Sample Output
11, 12, 13, 14, 24, 23, 22, 21, 31, 32, 33, 34, 44, 43, 42, 41, END
