Solution
Sure, here is a Python solution for the problem:
def is_prime(n):
if n <= 1:
return False
if n <= 3:
return True
if n % 2 == 0 or n % 3 == 0:
return False
i = 5
while i * i <= n:
if n % i == 0 or n % (i + 2) == 0:
return False
i += 6
return True
def unique_primes(lst):
unique_nums = list(set(lst))
primes = [num for num in unique_nums if is_prime(num)]
return primes
lst = [2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 11, 12, 13]
print(*unique_primes(lst))
In this solution, we first define a function is_prime(n) to check if a number n is prime. Then we define another function unique_primes(lst) to get the unique prime numbers from the list lst. In this function, we first get the unique numbers from the list using set(), then we use list comprehension to get the prime numbers from these unique numbers. Finally, we print the unique prime numbers.

Create a Python function that takes a list of integers as input andreturns a new list containing only the prime numbers from the input list.Provide a clear explanation of your implementation and include a test case.
The input begins with the number t of test cases in a single line (t<=10). In each of the next t lines there are two numbers m and n (1 <= m <= n <= 1000000000, n-m<=100000) separated by a space.OutputFor every test case print all prime numbers p such that m <= p <= n, one number per line, test cases separated by an empty line.ExampleInput:21 103 5Output:235735
