Recursion Answer: The same computation occurs repeatedly
Recursive Computation Answer: Solves a problem by using the solution to the same problem with
simpler values
In many cases, a recursive solution is easier to understand and implement correctly than an iterative
solution Answer: True
Occasionally, a recursive solution runs much slower than its iterative counterpart Answer: True
In most cases, the iterative and recursive approaches have comparable efficiency Answer: True
Measuring Execution Time Answer: long start= System.nanoTime(); //code to be executed long
elapsed = System.nanoTime() - start;
palidrome Answer: a word, sequence or phrase that reads the same forward as it does backwards,
for example words like 'dad', 'mom', 'madam' or numbers like '11', '121', or '99099'.
A word is a palindrome if Answer: 1. The first and last letters match
2. Word obtained by removing the first and last letters is a palindrome
, Fibonacci sequence Answer: A sequence of numbers in which each number is the sum of the
preceding two.
Measuring Execution Time Answer: long start = System.nanoTime();
//code to be executed
long elapsed = System.nanoTime() - start;
Sorting arrays is one of the most important operations in programming Answer: True
Algorithm Answer: - A sequence of instructions to solve a problem
-A process or set of rules to be followed in calculations or other problem-solving operations, especially
by a computer
Bubble Sort Answer: Moving through a list repeatedly, swapping elements that are in the wrong
order.
Selection Sort Answer: A sorting routine that uses a nested loop process to systematically select the
best value among the unsorted elements of the array for the next position in the array, starting with
position zero all the way to the end.
Insertion Sort Answer: A simple sorting algorithm that builds the final sorted array (or list) one item
at time. It is much less efficient on large lists than more advanced algorithms such as quicksort,
heapsort, or merge sort.
Merge Sort Answer: Sorts an array by cutting the array in half Recursively sorting each half, merging
the sorted values.
Which algorithm is associated with "Divide and Conquer"? Answer: Merge Sort
