The program qurt contains 3 context-dependant loops.

The number of iterations of the loops in the program is input dependant (a).

When run as is, the result is

No. of iterations for main_qurt1_sqrt_L1 = 19
No. of iterations for main_qurt2_sqrt_L1 = 0
No. of iterations for main_qurt3_sqrt_L1 = 19

If the loop is run, it is always run 19 iterations.
