The exam will close at 3:50 PM. Therefore, you must save your work before 3:50 PM. The multithreaded base 4 to binary transformation. You must complete the program below (using POSL X theads) that creates n theads (where n is the number of digits of the base 4 value from the inputi) to determine the birlary representation (string array) of the base 4 number from the input. Each child thread stores the string with the bits representing the assigned base 4 digit in a location accessible by the parent. thread The program's inout will be a string representing the base 4 number Given the following input 163 Each child thread uses the provided base4digToBin user-defined function to transform the assigned base 4 digit to bil For the previous input, the program creates three child processes: The first child thread transforms the base 4 digit " 1 " to " 01". The second child thread transform the base 4 digit " 0 " to " 00 ". The third child thread transform the base 4 digit "3" to "11". The expected output by the parent thread is: NOTES: . Not using POSl threads will translate into a penal ty of 100%. 2. You cannot modity the structure used to pass the arguments from the parent thread to the child threads. 3. Follow the instructions provided in the template fle to complete your solution. 4. You can always assume tha: the input will be valid
