# Challenge 163
#
# Task 2: Summations
# Submitted by: Mohammad S Anwar
#
# You are given a list of positive numbers, @n.
#
# Write a script to find out the summations as described below.
# Example 1
#
# Input: @n = (1, 2, 3, 4, 5)
# Output: 42
#
# 1 2 3 4 5
# 2 5 9 14
# 5 14 28
# 14 42
# 42
#
# The nth Row starts with the second element of the (n-1)th row.
# The following element is sum of all elements except first element of previous
# row.
# You stop once you have just one element in the row.
#
# Example 2
#
# Input: @n = (1, 3, 5, 7, 9)
# Output: 70
#
# 1 3 5 7 9
# 3 8 15 24
# 8 23 47
# 23 70
# 70
