In the figure, the circle stands for employed, the square stands for social worker, the triangle stands for truthful, study the figure with its regions and find the number of neither truthful nor illiterate people among the employed only.
Consider the program below which uses six temporary variables a, b, c, d, e and f.
a = 10
b = 20
c = 30
d = a + c
e = b + d
f = c + c
b = c + e
e = b + f
d = 5 + e
return d + f
Assuming that all the above operations take their operands from registers, the minimum number of registers needed to execute this program without spilling is:
A closed-loop system has the characteristic equation given by: $ s^3 + k s^2 + (k+2) s + 3 = 0 $.
For the system to be stable, the value of $ k $ is:
