Detailed explanation-1: -Explanation: Loop unrolling is a code optimization technique that avoids tests at every iteration of the loop.
Detailed explanation-2: -Loop unrolling is a code optimisation technique: That avoids tests at every iteration of the loop.
Detailed explanation-3: -Loop unrolling is a compiler optimization applied to certain kinds of loops to reduce the frequency of branches and loop maintenance instructions. It is easily applied to sequential array processing loops where the number of iterations is known prior to execution of the loop.
Detailed explanation-4: -Loop unrolling is a technique for attempting to minimize the cost of loop overhead, such as branching on the termination condition and updating counter variables.
