Step-by-Step Analysis
Question restated: Which of the following statements is true with reference to an algorithm’s runtime?
Option analysis:
- Option provided: 'A single algorithm can execute more quickly on a faster processor.'
This statement aligns with how real-world performance works. Runtime is generally measured as the actual time taken to run, which can be reduced when the processor is faster because each operation is completed more quickl......Login to view full explanationLog in for full answers

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. Hint: simplify your final answer as much as possible, and do not put spaces in your answer. Use juxtaposition for the multiplication operator, for example to write "nine times n" write "9n" not "9xn" or "9*n"; to write "four times (n+2)" write "4(n+2)", not "4x(n+2)" or "4*(n+2)". Do not write your answer in Big-O notation. Write the exact number of lines executed.
