Explain briefly Loop-invariant code motion of the commonly used code optimization techniques.
Loop-invariant code motion
If a quantity is calculated inside a loop during iteration and its value is similar for iteration, this can vastly improve efficiency to hoist this outside the loop and calculate its value just once before the loop begins. It is particularly significant with the address-calculation expressions generated through loops over arrays. For accurate implementation, such technique must be utilized with loop inversion, since not all code is safe to be hoisted outside the loop.
For illustration:
for (i=1; i≤10, i++){
x=y*2-(1)
.
}
statement 1 can be hoisted outside the loop assuming value of x and y does not modify in the loop.

How aliases are used in DNS? Explain. CNAME entries are analogous to a symbolic link in a file system- the entry gives an alias for other DNS entry. Corporation of expertsmind
Q. Diffrence between RISC and CISC architecture? CISCs provide better support for high-level languages since they include high-level language constructs such as CASE, CALL etc
A Padovan string P(n) for a natural number n is defined as: P(0) = ‘X’ P(1) = ‘Y’ P(2) = ‘Z’ P(n) = P(n-2) + P(n-3), n>2 where + denotes string concatenation. For a string of t
