Solution
The problem is asking to find the first non-repeating character in a given string. Here is a step-by-step solution in Python:
- Import the Counter class from the collections module.
from collections import Counter
- Define a function that takes a string as an argument.
def firstNonRepeatingCharacter(s):
- Inside the function, use the Counter class to count the frequency of each character in the string.
frequency = Counter(s)
- Iterate over the string. For each character, check its frequency. If the frequency is 1, return the character.
for char in s:
if frequency[char] == 1:
return char
- If no non-repeating character is found, return the message "Either all characters are repeating or string is empty".
return "Either all characters are repeating or string is empty"
- Call the function with a string as an argument to test it.
print(firstNonRepeatingCharacter('hello'))
This will output 'h', which is the first non-repeating character in the string 'hello'.
