War is peace. Freedom is slavery. Ignorance is strength As George Orwell wrote in 1984:


  War is peaceFreedom is slaveryIgnorance is strength


Write a program or function that takes in one of the six main words from the Orwell quote and outputs its counterpart.

Specifically:

[input] -&gt; [output]
war -&gt; peace
peace -&gt; war
freedom -&gt; slavery
slavery -&gt; freedom
ignorance -&gt; strength
strength -&gt; ignorance


No other input/output pairs are required.

You should assume the words are always fully lowercase, as above. Alternatively, you may assume the words are always fully uppercase: WAR -&gt; PEACE, PEACE -&gt; WAR, etc.
