Answer:
7 page faults
Explanation:
I have created a small Java program that can be seen in the attached picture below. This Java program uses an LRU algorithm in order to find the number of page faults within an array of page references from the references given in the question. Using these references, and the java program we can see that there are a total of 7 page faults. This can be seen in the output highlighted by red in the picture below.

def replace_at_index(txt,ind):
new_txt = ""
for x in range(len(txt)):
if x == ind:
new_txt += "-"
else:
new_txt += txt[x]
return new_txt
s = replace_at_index("eggplant", 3)
print(s)
