string copy_str = str; int num_of_dups = 0; for (int symbol = 0; copy_str[symbol] != '\0'; symbol++) { bool rep = false; for (int comp_symbol = symbol + 1; copy_str[comp_symbol] != '\0'; comp_symbol++) { if (copy_str[symbol] == copy_str[comp_symbol] && ( (copy_str[comp_symbol] >= 'A' && copy_str[comp_symbol] = 'a' && copy_str[comp_symbol]
