Method mismatch:

Write a static method named mismatch that accepts two Strings as parameters and returns

the number of mismatches. Each String is assumed to represent DNA sequence, that means

consists of capital A$,$ C$,$ G$,$ and T letters only. For a match we need A and T to be lined up and C

and $G$ to be lined up for every pair. For example, to get a mismatch A should line up with A$,$ C or

$G,$ or will not have a pair at all. See examples below.

Examples:

mismatch $("$ATCGAT$",$ "TAGCTA"$)$ returns $0$

ATCGAT

$|||||$

TAGCTA

mismatch $("$ATCGAT$",$ "TAGCAA"$)$ returns $1$

ATCGAT

$||||x|$

TAGCAA

mismatch $("$ATCGAT$",$ "TATCTT"$)$ returns $2$

ATCGAT

$||x||x$

TATCTT

mismatch $("$ATCG$",$ "TATCTT"$)$ returns $3$

ATCG

$||x|$

TATCTT

Note $1$: You can use the above examples in your main to check the methods works as intended.

Note $2$: You can assume a legit input to the method, so no need to check for input correctness.

Tip $1$: This method returns things, that means to check it you need to call it and store or print

result.

Tip $2$: When working with Strings methods like chartAt$($i$)$ and length$()$ can be useful.
