Split the string into a character array. Iterate over the character array. For each iteration, use the character as theMapkey,and check if the same character is present in the map, already. If the map key does not exist, the character has been encountered for the first time. Store it i...
In the above program, the length of the given string, str, is found using the string method length(). We loop through each character in the string using charAt() function which takes the index (i) and returns the character in the given index. We compare each character to the given char...
