Q
Q: If the array is [1, 2, 3, 4, 5] and the target is 3, what will be the mid index during the first iteration?
Solution: The mid index is calculated as (0 + 4) // 2 = 2, which corresponds to the value 3.
Steps: 5
Step 1: Identify the array, which is [1, 2, 3, 4, 5].
Step 2: Determine the starting index (left) and ending index (right) of the array. The left index is 0 (the first element) and the right index is 4 (the last element).
Step 3: Calculate the mid index using the formula (left + right) // 2. Here, it will be (0 + 4) // 2.
Step 4: Perform the calculation: (0 + 4) = 4, and then 4 // 2 = 2.
Step 5: The mid index is 2, which corresponds to the value 3 in the array.
