Count the number of Consonants and Vowels in a string

Vowels:-   a,e,i,o,u,A,E,I,O,U 
In this question, we have to count the number of consonants and vowels.

How to Approach :- 
For this, we must traverse the whole string while traversing take a character and check whether it is a consonant or vowel. If it is a consonant increase the count of consonants by 1 otherwise increase the count of vowels by 1.

 import java.util.Scanner;
 public class NumbersOfVowelsAndConsonants {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        String str = sc.nextLine();
        int vowels = 0, consonants =0;
        String lowerCase = str.toLowerCase();
        for (int i = 0; i <str.length(); i++) {
            char c = lowerCase.charAt(i);
            if (c == 'a' || c == 'e' || c == 'i' || c == 'o' || c == 'u')
                vowels++;
            else if (c > 'a' && c <= 'z')
                consonants++;
        }
        System.out.println("vowels = "+vowels);
        System.out.println("consonants = "+consonants);
    }
 }

Python

input_str = input("Enter a string: ")
vowels, consonants = 0, 0
for char in input_str:
    if char.lower() in ['a', 'e', 'i', 'o', 'u']:
        vowels += 1
    elif 'a'<char.lower()<='z':
        consonants += 1
print("Vowels:",vowels)
print("Consonants:",consonants)

Check whether a number is Seed of another number

 A number P is said to be the seed of another number Q if multiplying P with its digits equates to Q. Ex:-  123 is seed of 738 as    123 * 1 * 2 * 3 = 738  Java 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 public class Seed{ public static void main (String[] args){ int num1 = 123 , num2 = 738 ; num1 = Math. min (num1,num2); num2 = Math. max (num1,num2); System. out . println (checkSeed(num1, num2)); } public static boolean checkSeed ( int num1, int num2){ int seed = num1; while (num1> 0 ){ seed = seed * (num1% 10 ); num1 = num1 / 10 ; } if (seed==num2) return true ; else return false ; } } Python def checkSeed(num1,num2): seed = num1 while num1 > 0 : seed = seed * (num1 % 10 ) num1 = num1 // 10 if seed == n
