Can a loop be O(1)?
Yes, if the loop has fixed, hardcoded boundaries (e.g., for(i=0; i<100; i++)) that do not scale when the input data scales, it is considered O(1).

It means the algorithm takes the exact same amount of time to execute, regardless of whether the input size is 10 or 10 million.
Yes, the computer calculates the exact memory address instantly using the index and the size of the data type, requiring no traversal.
A Hash Map uses a mathematical hashing function to convert the key directly into an array index, allowing for instant memory retrieval.
