1.1
Is there a problem with the following algorithm for i = N + 1?
i=1;
while (i<=N && a[i]==b[i]) { i=i+1;}
if (i>N) {equal = true;} else {equal = false}
1.4
Write a program that finds a substring in a string (on a character by character basis, not using
built-in functions). Do this either in Java (if you can) or in Excel. Hint: with Excel, you have
to write iterations/loops spatially, i.e. use one cell per iteration and copy the body of the loop
into each cell.
1.5
Implement the Needleman-Wunsch algorithm (again, either in Java or in Excel)
1.6
Write down the algorithm for overlay matches.
3.4
Write a small clustering program (you can probably also simulate a simple clustering
algorithm with Excel). Print the expression matrix ordered according to the clustering (either
numerically or graphically, if you can). Vary clustering parameters and observe differences in
the result.

行行好吧！
