Scala Programming: Find maximum difference between two elements in a given array of integers such that smaller element appears before larger element
Scala Programming Array Exercise-38 with Solution
Write a Scala program to find maximum difference between two elements in a given array of integers such that smaller element appears before larger element.
Example:
Input:
nums = { 2, 3, 1, 7, 9, 5, 11, 3, 5 }
Output:
The maximum difference between two elements of the said array elements
10
Sample Solution:
Scala Code:
object Scala_Array {
def diff_between_two_elemnts(nums: Array[Int]): Int = {
var diff_two_elemnts = Integer.MIN_VALUE;
for (i <- 0 to nums.length - 1) {
for (j <- i + 1 to nums.length - 1) {
diff_two_elemnts = Integer.max(diff_two_elemnts, nums(j) - nums(i));
}
}
return diff_two_elemnts;
}
def main(args: Array[String]): Unit = {
val nums = Array(2, 3, 1, 7, 9, 5, 11, 3, 5);
println("Original array:")
for (x <- nums) {
print(s"${x}, ")
}
System.out.print(
s"\nThe maximum difference between two elements of the said array elements: ${diff_between_two_elemnts(nums)}"
)
}
}
Sample Output:
Original array: 2, 3, 1, 7, 9, 5, 11, 3, 5, The maximum difference between two elements of the said array elements: 10
