A programmer needs to choose between two algorithms, Algorithm A and Algorithm B, to solve a problem.
Algorithm A takes 500 milliseconds to process 1,000 items, while Algorithm B takes 300 milliseconds to process the same number of items. However, Algorithm A uses less memory than Algorithm B.
Explain one situation where the programmer might prefer Algorithm A over Algorithm B, even though it is slower.

Consider the following pseudocode, which asks the user to input 5 numbers and stores them in a list:
DECLARE list AS []a ← USERINPUTAPPEND(a, list)b ← USERINPUTAPPEND(b, list)c ← USERINPUTAPPEND(c, list)d ← USERINPUTAPPEND(d, list)e ← USERINPUTAPPEND(e, list)
