#accepting n
n=int(input("Enter n: "))
#creating a dictionary having first n counting numbers as key and their squares as value
squares={i:i*i for i in range(1,n+1)}

#initializing a sample value_list
value_list=[1,2,2,2,3,4,5,5]
#removing duplicate values and finding the number of non duplicate elements in this list and assigning it to distinct_values
distinct_values=len(set(value_list))
#printing distinct_values
print(distinct_values)
