The time complexity of the algorithm is exponential, specifically O(2n), indicating that the algorithm's runtime grows exponentially with the input size.
The time complexity of a while loop in an algorithm is typically represented as O(n), where n is the number of iterations the loop performs.
To determine tight asymptotic bounds for an algorithm's time complexity, one can analyze the algorithm's performance in the best and worst-case scenarios. This involves calculating the upper and lower bounds of the algorithm's running time as the input size approaches infinity. By comparing these bounds, one can determine the tightest possible growth rate of the algorithm's time complexity.
The time complexity of the Count Sort algorithm is O(n k), where n is the number of elements in the list and k is the range of the integers in the list.
To determine the lower bound for a problem or algorithm, one can analyze the best possible performance that any algorithm can achieve for that problem. This involves considering the inherent complexity and constraints of the problem to establish a baseline for comparison with other algorithms.
