s1 is "Testing in process" and s2 is "This is a small driver"
The results of comparing is:
s2==s1 yields false
s2! =s1 yields true
s2>s1 yields true
s2<s1 yields false
s2<=s1 yields false
s2>=s1 yields true
s1 += s2 yields s1 = Testing in processThis is a small driver
s1 after s1 [0] = t and s1 [1] =E

find and delete in s1 s2
