Write a Scala program to find all combination of four elements of a given array whose sum is equal to a given value

object Scala_Array {
  def main(args: Array[String]): Unit = {
    val nums = Array(10, 20, 30, 40, 1, 2);
    println("Original array:")
    for (x <- nums) {
      print(s"${x}, ")
    }
    val n = nums.length;
    // given value
    val s = 53;
    println("\nGiven value: " + s);
    println("Combination of four elements:");
    // Find other three elements after fixing first element
    for (i <- 0 to n - 4) {
      // Find other two elements after fixing second element
      for (j <- i + 1 to n - 3) {
        // Find the fourth element after fixing third element
        for (k <- j + 1 to n - 2) {
          // find the fourth
          for (l <- k + 1 to n - 1) {
            if (nums(i) + nums(j) + nums(k) + nums(l) == s)
              println(
                "\n" + nums(i) + " " + nums(j) + " " + nums(k)
                  + " " + nums(l)
              );
          }
        }
      }
    }

  }
