Given a string s and a character letter, return the percentage of characters in s that equal letter rounded down to the nearest whole percent.
LeetCode Problem - 2278
class Solution {
public int percentageLetter(String s, char letter) {
double countOfletter = 0; // Initialize a counter to keep track of the occurrences of the specified letter
// Iterate over each character in the string 's'
for (char ch : s.toCharArray()) {
// If the current character matches the specified 'letter', increment the counter
if (ch == letter) {
countOfletter++;
}
}
// Calculate the percentage of the specified letter in the string
double len = s.length(); // Get the length of the string
int result = (int) ((countOfletter / len) * 100); // Calculate the percentage and cast it to an integer
return result; // Return the calculated percentage as an integer
}
}
