Assuming that str is not null, what is the purpose of the code segment below? String look = "m";
int x = 0;
for (int i = 0; i < str. length(); i++)
{
String temp = str. substring(i, i+1);
if (temp. equals(look))
{
x++;
}
}
System. out. println(x);
Searching until a particular substring is found
Computing a total sum
Comparing adjacent values
