Computer Science Assume we have a program with the following source code, where S1, S2, S3, S4 and S5 are systems calls we can monitor at run-time. 1) S1 2) while (S2) 3) { S3; 4) if (S4) 5) S5; 6)...

Assume we have a program with the following source code, where S1, S2, S3, S4 and S5 are systems calls we can monitor at run-time.

1) S1

2) while (S2)

3) { S3;

4) if (S4)

5) S5;

6) else S2;

7) if (...) S2;

8) else S5

9) }

10) S2;

11) S3;

List all the possible 3-grams of system calls (Here we don’t consider Program Counter (PC) or state information)
