The set of instructions that defines an algorithm in the formal, strict sense is: B. x = 3; while(x < 5) do (x <-- x + 1).
What is an algorithm?
An algorithm can be defined as a standard formula (procedures) which comprises a set of finite steps and instructions that is used for proffering solutions to a problem on a computer under appropriate conditions.
In this scenario, the set of instructions that defines an algorithm in the formal, strict sense is given by this syntax:
x [tex]\leftarrow[/tex] 3;
while (x < 5) do
(x [tex]\leftarrow[/tex] x + 1)
