Question:
How many passes does an insertion sort algorithm take for sorting an array of ‘n’ elements?
How many passes does an insertion sort algorithm take for sorting an array of ‘n’ elements?
Show Hint
Insertion sort starts from index 1 to \(n-1\), thus requires \(n-1\) passes.

- \(\dfrac{n}{2}\)
- \(n\)
- \(n - 1\)
- \(n + 1\)
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Insertion sort compares each element with the elements before it, starting from the second position. Therefore, for \(n\) elements, it takes \(n - 1\) passes.
