P10_Transpose.py

# Given a 2D array A, your task is to convert all rows to columns and columns to rows.
#
# Input:
# First line contains 2 space separated integers, N - total rows, M - total columns.
# Each of the next N lines will contain M space separated integers.
#
# Output:
# Print M lines each containing N space separated integers.
#
# Constraints:
# 1≤N≤10
# 1≤M≤10
# 0≤A[i][j]≤100 where
# 1≤i≤N and
# 1≤j≤M
#
# SAMPLE INPUT
# 3 5
# 13 4 8 14 1
# 9 6 3 7 21
# 5 12 17 9 3
#
# SAMPLE OUTPUT
# 13 9 5
# 4 6 12
# 8 3 17
# 14 7 9
# 1 21 3
