Transcribed Image Text:Question: If the three operations were combined, O(logN) + O(N) * O(logN) +1, the overall algorithm cost
would be:
A. O(N)
B. O(logN)
C. O(logN) + O(N)
D. O(NlogN)
What is the dominate term of each function?
3n?+4n-3
7n + 4n? -7n + 5
5nlog(n) + 2n– 4

1. Termination Condition
2. Call the Clone (same function)
3. Move towards Termination Condition
Label the Recursion Requirements.
Show the Activation Stack for n = 4.

return true;
if (charAt (0)
// check first and last char of String:
// if same then do same for substring
// for substring and carry on this
// remove first and last char.
return isPal (s.substring (1, 3.length ()-1));
