This program is supposed to read from a text file and create an array with the size of the first number in the file and fill it with the other number which is going to be zero and ones

if the value is zero it means the bulb is defective if it's equal to 1 the bulb is working this assignment is made to get familiar to using threads so the recursion of the array splitting has to work that way by the end of the code we want to know how many threads were created and trace back the zeros to find there index on the first array and displaying it

the issue that I'm having is that I can't figure out how to trace does values down when I have to threads running and doing each recursion concurrently can anyone help me out with this

Thank you.
