Round 3: Tossup 19

While optimizing a compiler, these constructs may be subject to “fission” or “fusion” to best (15[1])utilize locality of reference. Java supports the “enhanced” version of these constructs which do not require the declaration of an index. These constructs can be optimized by “unrolling” them to increase execution speed. An N-squared runtime is created when (*) “nesting” two of these constructs, which can be exited using a (-5[1])“break” statement. (10[1])When a conditional statement defines these constructs, they are declared using (10[1])the keyword “while.” For 10 points, name these constructs that repeat a section of code multiple (10[1])times. ■END■
