Q: What is the time complexity of finding the maximum element in an unsorted array?
Solution: To find the maximum element in an unsorted array, you must check each element, resulting in O(n) time complexity.
Steps: 7
Step 1: Understand that an unsorted array means the elements are in no particular order.
Step 2: To find the maximum element, you need to look at each element in the array.
Step 3: Start from the first element and compare it with the next one to see which is larger.
Step 4: Continue this process for all elements in the array until you reach the end.
Step 5: Keep track of the largest element you find during these comparisons.
Step 6: Once you have checked all elements, the largest one you tracked is the maximum element.
Step 7: Since you had to check each element once, the time it takes grows with the number of elements, which is why we say the time complexity is O(n).
