WebApr 13, 2024 · First, the for loop defines the loop control variables that it needs to define the number of times it will execute. In the case of the above code, the control variable is i. This is a notable difference from the while loop whose statement does not provide a set number of loops nor any control variables. WebLoops are considered as dynamic if they depend on input size otherwise they are static statements, everything within a loop is considered as static statement. Each static statement is considered as 1 unit of time. To calculate overall complexity of loop: find number of iterations it makes * number of static statements (1 unit each)

"WebFor more complex code than a simple sum, however, there won’t be that much of a relative difference, as the calculations themselves would take more time. Imperative code is a lot more verbose in most cases. Five code lines for a simple sum are too much, and reduce is just a one-liner. " - For loop vs while loop time complexity
