DCP-27: Is It Prime? Back to All Problems

Beginner Math > Basic Math


A prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself. Below is a chart of numbers up to 100 and yellow marked numbers are prime numbers. ![primes][1] We want you to write a program that can check whether a given input number is prime number or not. All number will be in the range **0 <= N <=10000**. Input: ------ Input starts with an integer **T (≤ 5000)**, denoting the number of test cases. Each test case will have one line containing the number to test. Output: ------- For each test case, print either “Yes” (without quotes) or “No” (without quotes). If the input number is prime number then print “Yes”, otherwise print “No”. Please check sample input/output to get an idea. Sample Input ------------ 3 97 55 1000 Sample Output ------------- Yes No No [1]: https://s3-ap-southeast-1.amazonaws.com/devskillimagestorage/questionimages/8a279e47-68b0-c989-90c5-08d2e286f36c_b929388111cd4762bbb4ee94dc73332d_W650xH487.jpg
