Asked in companies
Given a string ‘STR’ which consists of uppercase and lowercase characters and spaces. Count the number of consonants in the string.
A consonant is an English alphabet character that is not vowel (a, e, i, o, and u). Examples of constants are b, c, d, f, etc.
Example :
Given string 'STR' : ‘Coding Ninjas’ there are 8 consonants i.e ‘C’,’d’,’n’,’g’,’N’,’n’,’j’,’s’, because these characters do not belong to set above mentioned set of vowels.
Problem approach
Step 1 : First convert the given string into lowercase for uniformity while counting vowels, consonants, and
whitespaces.
Step 2 : This can be done by using .toLowerCase() in Java.
Step 3 : After that traverse the entire modified string by applying the following conditions -
If any vowel then increment the vowel counter
Else if any consonant then increment the consonant counter
Else if any whitespace then increment the whitespace counter
