The diagram below corresponds to a 100-lme; high-level language program with a single loop that...

In the given diagram, each diamond represents a decision point, and each square represents a process step. Assuming the decisions and paths within the loop create unique paths, the complexity can be calculated as follows: if each decision point splits into 2 paths and there arennndecision points within the loop, then the number of possible paths for one iteration can be represented as2n2^n2n. Given that the loop executes 20 times, the total number of paths would be approximately(2n)20(2^n)^{20}(2n)20. Since there are multiple decision points, the complexity quickly escalates, leading to a very high number of possible paths, hence 1014 is a plausible approximation.
