What is ternary search in C?
What is ternary search in C?
Ternary search is a decrease(by constant) and conquer algorithm that can be used to find an element in an array. It is similar to binary search where we divide the array into two parts but in this algorithm, we divide the given array into three parts and determine which has the key (searched element).
What is meant by ternary search?
A ternary search determines either that the minimum or maximum cannot be in the first third of the domain or that it cannot be in the last third of the domain, then repeats on the remaining two thirds. A ternary search is an example of a divide and conquer algorithm (see search algorithm).
Is ternary search faster than binary?
Thus, we can say that Binary search is faster than Ternary search. This happens because of the increase in the number of comparisons in Ternary search. In simple words, the reduction in the number of iterations in Ternary search is not able to compensate for the increase in comparisons.
How do I find a ternary tree?
However, ternary search trees are more space efficient compared to standard prefix trees, at the cost of speed….Ternary search tree.

| Algorithm Average Worst case Search O(log n) O(n) Insert O(log n) O(n) Delete O(log n) O(n) |
What is the complexity of ternary search?
At first look, it seems that ternary search might be faster than binary search as its time complexity on an input containing n items should be O(log3n), which is less than the time complexity of binary search O(log2n). Before analyzing this claim, let’s take a look at its C, Java, and Python implementation first.
How does ternary search differ from binary search?
In binary search, we keep dividing the sorted array into two halves (and determine which one has the key) until we find the element we’re searching for, whereas, in ternary search, we divide the array into three halves (and determine which one has the key) until we find the element we’re searching for.
What is ternary search time complexity?
The complexity of Ternary Search Technique Time Complexity: O(log3 n)
How many comparisons are in ternary search?
4 comparisons
So, ternary search makes 4 comparisons whereas, in binary search, we only make a maximum of 2 comparisons in each iteration.
What is the time complexity of a ternary search?
What is binary search in C with example?
Also, you will find working examples of Binary Search in C, C++, Java and Python. Binary Search is a searching algorithm for finding an element’s position in a sorted array. In this approach, the element is always searched in the middle of a portion of an array.
