So now that we know how to tell if a variant is normalized, we simply need to manipulate the variant till the rightmost ends of the alleles are not the same, apply truncation to the superfluous nucleotides on the left side of the variant to obtain a normalized variant.

The algorithm to normalize a variant; biallelic or multiallelic is as follows:
