Sorting algorithms can help you find the first repeating character in a string inO(n Log n)time. However, you can loop through the string and hash the characters usingASCIIcodes, run the loop on the hash array, and find the minimum position of any repeated character. ...
You are given a string str consisting of lowercase Latin letters. Find the first non-repeating character in str. Note: You have to traverse the string only once. See original problem statement here Tets Case: Input: prepbytes Output: 1 Explanation: In the string 'prepbytes', we start trave...
