Asked in companies
Given a string ‘STR’ consisting of lower case English letters, the task is to find the first non-repeating character in the string and return it. If it doesn’t exist, return ‘#’.
For example:
For the input string 'abcab', the first non-repeating character is ‘c’. As depicted the character ‘a’ repeats at index 3 and character ‘b’ repeats at index 4. Hence we return the character ‘c’ present at index 2.
Problem approach
- Create a hash map that maps characters to their frequencies.
- Traverse the string.
- Increase the count of the current character.
- Traverse the string again and check whether the frequency of the current character is 1.
- Print the first character that has a frequency of 1.
