The goal of this program is to encode an incoming message using a special binary encoding method. In this method, the input message, consisting of ASCII characters, is transformed into blocks of 0s separated by spaces. The first block is either 0 or 00, where 0 represents a series of 1s and the absence of 0 represents a series of 0s. The second block contains the number of 0s corresponding to the number of bits in the series. For example, the character 'C' is encoded as "0 0 00 0000 0 00," where 'C' in binary is 1000011. The program should handle input messages with up to 100 ASCII characters and output the encoded message accordingly.
This function takes a message as input, which is a string, and converts each character of the message into its binary representation. It iterates over each character of the message using a for...of loop and appends the binary representation of each character to the binary variable. The binary representation of each character is obtained using the charCodeAt(0) method, which returns the Unicode value of the character, and then converted to a binary string using the toString(2) method. The resulting binary strings are padded with leading zeros using the padStart() method to ensure that each binary representation has a length of 7. Finally, the function returns the concatenated binary string.
This function takes a binary string as input, which represents a binary sequence, and converts it into a unary representation. It initializes an empty array called allSeries to store the unary sequences. The function uses a regular expression (/(.)\1*/g) with the match() method to find consecutive groups of the same character in the binary string. The groups variable holds an array of these consecutive groups. For each group, the function creates a unary series based on the first character of the group. If the first character is '1', the first block of the unary series is set to "0"; otherwise, it is set to "00". The second block of the unary series is set to a sequence of '0' characters that has the same length as the group. The first and second blocks are concatenated with a space in between, and the resulting series is added to the allSeries array. Finally, the function joins all the unary series in the allSeries array into a single string separated by spaces and returns it.
The remaining code after the function definitions reads input from the user using readline(), assigns it to the message variable, and then calls the toBinary() function to convert the message to binary. The resulting binary string is stored in the binary variable. After that, the toUnary() function is called with the binary string as input to convert it into a unary representation. The resulting unary string is stored in the unary variable. Finally, the unary string is printed to the console using console.log().
Please note that this code assumes the presence of some I/O functionality, such as the readline() function, which might not be available in all JavaScript environments.
