Perform window to viewport transformation for the point (20,15). Assume that $(X_{wmin}\ ,Y_{wmin} )$ is $(0,0)$ ; $(X_{wmax}\ ,Y_{wmax} )$ is $(100,100)$ ; $(X_{vmin}\ ,Y_{vmin} )$ is $(5,5)$ ; $(X_{vmax}\ ,Y_{vmax} )$ is $(20,20)$ . The value of $x$ and $y$ in the viewport is $x=4,y=4$ $x=3,y=3$ $x=8,y=7.25$ $x=3,y=4$

Help me understand this statement from Theory of Computation by Peter Linz "If between two vertices vi and vj there is any walk labeled w, then there must be some walk labeled w of length no more than Λ + (1 + Λ) |w|, where Λ is the number of ... of the walk." I am also having difficulty in understand extended transition function for an nfa , would be really helpful if someone could explain that.

This is the statement for Divisibility test of 11. Add and subtract digits in an alternating pattern (add digit, subtract next digit, add next digit, etc). Then check if that answer is divisible by 11. This is the proof that I found : If x is divisible by 11, then x ≡ 0 (mod 11). Thus ... -------------------------------------------- Now, I didn't understand the proof starting from But.

Folks, as the global or static variables are stored in data section of process and their scope is throughout the program, but once the main() function returns or complete execution or when whole program is executed and activation record of main() is ... section? Does global variable stays or the whole process is deleted including global variables from memory once the program ran to completion?
