executing for loop

I have a pseudo code,please can u code it for me

sim-0;

str1=A1(First imagename in the dataset)

for loop for 1 to 80 images

str2 from J (convert from number to string)

string compare str1 and str2

calculate Precision and recall (if strcmp is 0 )

if it is not similar, repeat the process

my J value ranges from 1 t0 80

I have 80 images in dataset

What are you calculating the precision of? Or would it be the case that here when you write "Precision", you mean a calculation of how well the images match?
