# In this Kata we will play a classic game of Tug-o-War!

# Two teams of 5 members will face off, the strongest of which will prevail.
# Each team member will be assigned a strength rating (1-9), with the most powerful members having a rating of 9.
# Your goal is to determine, based on the cumulative strength of the members of each team, which team will win the war.

# The teams will be represented by an array of arrays:

# [[5,0,3,2,1], [1,6,8,2,9]]  # 11 < 26 ; "Team 2 wins!"
# Your task is to return a string with which team won or if it was a tie.

# If team one is stronger, return the string "Team 1 wins!"
# If team two is stronger, return the string "Team 2 wins!"
# If the two teams are of equal strength, the team with the strongest Anchor
# (the member furthest from the center of the rope) will win.
# In the above example, the member with strength 5 is team one's Anchor and strength 9 is team two's Anchor.

# If the teams and the Anchors are both of equal strength, return the string "It's a tie!"
# The Anchors are members in each end of the rope:
