[@abhijitkarmakar6328]

In the first coding question, he using array hashing and character ASCII value, since it was mentioned that we only have lowercase characters, so the person created a array of size 26 to denote the each character index values. He was substracting a because ASCII range for 65-90(a-z), so the hash array would look something like int [] hashArray = {0,0,0,......0} , 26 zeros on each index. Now when he gets the index of each char by substracting a. For example if we want index of b, it will be 66-65 = 1 and then incrementing the value at that index, after computation he would have an array in which index have count of the characters.
Now he could easily iterate through the array for each character and find if count of the char is 1 then return the index else if not found return -1;

String sentence = "abcdcaf";
for (int i = 0; i < sentence.length(); i++) {
int count = 0;
for (int j = 0; j < sentence.length(); j++) {
if (sentence.charAt(i) == sentence.charAt(j)) {
count = count + 1;
}
}
if (count == 1) {
System.out.println(sentence.charAt(i));
break;
}
}

so what about the return statement and the lowercase issues..

[@divyanshkaushik6265]

public class FirstNonRepeatingCharacter {
public static int firstNonRepeatingCharacter(String str) {
Map frequencyMap = str.chars()
.mapToObj(c -> (char) c)
.collect(Collectors.groupingBy(c -> c, LinkedHashMap::new, Collectors.counting()));
Optional firstNonRepeatingChar = frequencyMap.entrySet()
.stream()
.filter(entry -> entry.getValue() == 1)
.map(Map.Entry::getKey)
.findFirst();
return firstNonRepeatingChar.map(c -> str.indexOf(c)).orElse(-1);
}
public static void main(String[] args) {
String input = "abcdcafb";
int result = firstNonRepeatingCharacter(input);
System.out.println(result);
}
}
