    // Sample code to perform I/O:
     
    process.stdin.resume();
    process.stdin.setEncoding("utf-8");
    var stdin_input = "";
     
    process.stdin.on("data", function (input) {
      stdin_input += input;                               // Reading input from STDIN
    });
     
    process.stdin.on("end", function () {
      main(stdin_input);
    });
     
    function main(input) {
      lines = input.split('\n') // Array of input lines

      const N = lines[0]; // Count of values
      const values = lines[1].split(' '); // Array of values
      const K = lines[2]; // The value to search for

      // For loop solution
      for (let index = 0; index < values.length; index++) {
        if (values[index] === K) {
          console.log(index);
          break;
        }
      }

      // While loop solution
      let index = 0;
      while (index < values.length) {
        if (values[index] === K) {
          console.log(index);
          break;
        }
        index++;
      }

      // Built-in solution
      console.log(values.indexOf(lines[2]));
     
      // Least amount of lines
      console.log(lines[1].split(' ').indexOf(lines[2]));
    }

Thanks man

Line 40 -44 are they from the question itself?
