Paste code below in site's console and then type run() to automatically solve binary problems. To stop type stop() in the console and press enter.
The code:
// maps numbers to button idx on calculator
const calculatorMap = [2, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13];
var listinerId = 0;

function run() {
  listinerId = setInterval(() => {
    // progress to next level
    document.querySelector(".window.modal.fade-enter-done>.modal-body>button")?.click();

    // get bottom problem
    const problem = document.querySelector(".problem:not(.blank-exit)");
    // if problem exists solve it
    if (problem) {
      // get problem wrapers
      const div = problem.querySelector(".problem-wrapper>.sub-wrapper");

      // check problem type
      if (problem.querySelector(".isProblem")) {
        // user has to enter digits

        // open calculator
        div.querySelector(".digits").click();

        // bits to number
        let sum = 0;
        div.querySelectorAll(".bit").forEach((e, i) => {
          sum += Number(e.innerText) * 2 ** (7 - i);
        });

        console.log("answer:", sum);

        // select numbers on calculator
        Array.from(String(sum), Number).forEach((e) => {
          document.querySelector(`.calculator :nth-child(${calculatorMap[e]})`).click();
        });

        // submit
        document.querySelector(`.calculator :nth-child(3)`).click();
      } else {
        // user has to flip bits

        let correct = Number(div.querySelector(".digits").innerText);

        // convert correct val to 8 bit array of bool
        let correctBin = new Array(8).fill(false);
        for (let index = 7; correct > 0 && index >= 0; index--) {
          correctBin[index] = Boolean(correct % 2);
          correct = Math.floor(correct / 2);
        }

        console.log("answer:", correctBin);

        div.querySelectorAll("button.bit").forEach((e, i) => {
          // if wrong state then flip bit
          if ((e.innerText == "1") != correctBin[i]) {
            e.click();
          }
        });
      }
    }
    // wait 0.5s
  }, 500);
}

function stop() {
  clearInterval(listinerId);
