Prime number within a given range
Detailed guide and Python implementation for the 'Prime number within a given range' problem.
Problem Statement
Write a function primes_in_range(a, b) that takes two integers a and b (where a <= b) and returns a list of all prime numbers in the range [a, b] inclusive, in ascending order.
- •1 <= a <= b <= 10^4
Examples
a = 10, b = 30
[11, 13, 17, 19, 23, 29]
The prime numbers between 10 and 30 are 11, 13, 17, 19, 23, and 29.
a = 1, b = 10
[2, 3, 5, 7]
The prime numbers between 1 and 10 are 2, 3, 5, and 7.
a = 4, b = 4
[]
4 is not prime, so the result is an empty list.
