The problem can be solved with a simple application of “while” loop: <sxh> L = input(“Give L : ”);
Rd = L; steps = 0; while Rd > 0.1*L;
Rd = Rd * 2.0/3.0 steps=steps+1;
endwhile printf(“One has to make %d steps\n”, steps); </sxh>
<texit> \begin{lstlisting} L = input(“Give L : ”);
Rd = L; steps = 0; while Rd > 0.1*L;
Rd = Rd * 2.0/3.0 steps=steps+1;
endwhile printf(“One has to make %d steps\n”, steps); \end{lstlisting} </texit>
