WebMar 6, 2024 · Merge Sort’s time complexity is determined by the number of comparisons that occur through the algorithm. Like most “divide and conquer” algorithms, one of its terms is logarithmic. WebIn computer science, the time complexity of an algorithm is expressed in big O notation. Let's discuss some time complexities. O (1): This denotes the constant time. 0 (1) usually means that an algorithm will have constant time regardless of the input size. Hash Maps are perfect examples of constant time. O (log n): This denotes logarithmic time.
