The given co‎de is written in Python.

def checkPrime(n):

   c=0

   for i in range(1,n+1):

       if n%i==0:

           c+=1

   if c==2:

       return True

   return False

n=int(input("Enter n - "))

for i in range(1,n+1):

   if checkPrime(i):

       print(i * i,end=" ")

   else:

       print(i,end=" ")

The checkPrime(n) function checks whether a number is prime or not. The value of n is taken as input. Inside the loop, this function is called. If the number is prime, square of the number is printed or else, the original number is printed.
