Answer:
int min
if (x<=y) then
min=x
else
min=y
endif
if (min>=z) then
min=z
endif
Step-by-step explanation:
I wrote a simple, generic piece of code that first compares the x and y variables and assigns to min the smallest of the two values, then it compares the min variable to the third value and check if the value stored in min is bigger than z, in that case, it means that z is the smallest of all three and it assigns the value of z into min. I took into consideration the possibility that two or the three numbers be equal, which it will still throw the smallest values of the three.
