Determine if String Halves Are Alike java solution
You are given a string s of even length. Split this string into two halves of equal lengths, and let a be the first half and b be the second half.
Two strings are alike if they have the same number of vowels ('a', 'e', 'i', 'o', 'u', 'A', 'E', 'I', 'O', 'U'). Notice that s contains uppercase and lowercase letters.
Return true if a and b are alike. Otherwise, return false.
Example 1:
Input: s = "book" Output: true Explanation: a = "bo" and b = "ok". a has 1 vowel and b has 1 vowel. Therefore, they are alike.
Example 2:
Input: s = "textbook" Output: false Explanation: a = "text" and b = "book". a has 1 vowel whereas b has 2. Therefore, they are not alike. Notice that the vowel o is counted twice.
Constraints:
2 <= s.length <= 1000s.lengthis even.sconsists of uppercase and lowercase letters.
Solution:
class Solution {
public boolean halvesAreAlike(String s) {
int[] vowel={'a', 'e', 'i', 'o', 'u', 'A', 'E', 'I', 'O', 'U'};
int count1=0,count2=0;
for(int i=0; i<s.length()/2; i++)
{
for(int j=0; j<vowel.length; j++)
{
if(s.charAt(i)==vowel[j])
{
count1++;
}
}
}
for(int i=s.length()/2; i<s.length(); i++)
{
for(int j=0; j<vowel.length; j++)
{
if(s.charAt(i)==vowel[j])
{
count2++;
}
}
}
if(count1==count2)
return true;
else
return false;
}
}
