Round 3: Tossup 19

While optimizing a compiler, these constructs may be subject to “fission” or “fusion” to best utilize locality (15[1])of reference. Java (15[1])supports the “enhanced” version of these constructs (15[1])which do not require the declaration of an index. These (-5[1])constructs (-5[1])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 “break” statement. When a conditional (10[1])statement defines these constructs, they are (10[1])declared using the keyword “while.” For 10 points, name these constructs that repeat a section of code multiple times. ■END■
