# Given two strings ss and tt of equal length, the Hamming distance between ss and tt, denoted dH(s,t)dH(s,t),
#  is the number of corresponding symbols that differ in ss and tt. See Figure 2.

# Given: Two DNA strings ss and tt of equal length (not exceeding 1 kbp).
# Return: The Hamming distance  dH(s,t)
