How To Find First Repeated And Non-Repeated Character In A String? Step 1 : Define one HashMap called charCountMap with Character as key and Integer as value. This map will hold the characters and their count in the given string. Step 2 : Convert inputString to char array called strArray . Step 3 : Iterate through all chars of strArray and update their occurrences in charCountMap . Step 4 : Iterate through all chars of strArray and check their count in charCountMap . Any first occurri...
