Questions & Step-by-Step Solutions

What is the time complexity of linear search in an unsorted array?
  • Step 1: Understand what linear search is. It means looking at each item in the array one by one.
  • Step 2: Know that in an unsorted array, you have to check every element to find the target value.
  • Step 3: If the array has 'n' elements, you might have to check all 'n' elements in the worst case.
  • Step 4: The time it takes to check each element adds up, leading to a total time of O(n).
  • Step 5: Conclude that the time complexity of linear search in an unsorted array is O(n).
