# DCP-423: Prime Magical Number Back to All Problems

Easy Beginners Problems > Ad-hoc

A number is called **Prime Magical Number** if it contains at least one prime digit in its decimal representation. for example: 124, 123 , 256 are Prime Magical Numbers as they contain at least one prime digit in their representation. Whereas 100 , 410, 698 are not Prime Magical Number as there is no prime digit in their representation.<br> You are given an integer **N**. Your task is to count total Prime Magical Number which are less than or equal to **N**.<br> ***Note: {2,3,5,7} are prime digit.*** Input: ------ Input starts with an integer **T (1<=T<=20)**, denoting the number of test cases. Each case contains an integer **N (1 ≤ N ≤ 100000)**. Output: ------- For each case of input, output the count of total **Prime Magical Number** which are less than or equal to **N**. Sample Input ------------ 1 5 Sample Output ------------- 3 ---------- **Sample Explanation:**<br> Prime Magical Number which are less than or equal to 5 are: 2,3,5. So, total = 3.<br>
