Consider the same method again:

public boolean isprefix(String s1, String s2) {

int i = 0;
if(s1.length > s2.length)
return false;

while(i < s1.length) {
if(s1[i] != s2[i])
return false;
i++;
}
return true;
}

Use the active operation approach and determine the exact number of times the active operation is executed in the worst case.  Express your answer in terms of n, the length of the string s1.
