Scala Programming: Find the second smallest element in an array
Scala Programming Array Exercise-20 with Solution
Write a Scala program to find the second smallest element from a given array of integers.
Sample Solution:
Scala Code:
object Scala_Array {
def main(args: Array[String]): Unit = {
var my_array = Array(10789, 2035, 1899, 1456, 2013,1458, 2458,
1254, 1472, 2365,1456, 2165, 1457, 2456);
println("Orginal array:")
for ( x <- my_array) {
print(s"${x}, ")
}
var min = Int.MaxValue
var second_min = Int.MaxValue
for (i <- 0 to my_array.length-1)
{
if(my_array(i)==min){
second_min=min;
} else if (my_array(i) < min) {
second_min = min;
min = my_array(i);
} else if (my_array(i) < second_min) {
second_min = my_array(i);
}
}
println("\nSecond lowest value of the said array: " + second_min);
}
}
Sample Output:
Orginal array: 10789, 2035, 1899, 1456, 2013, 1458, 2458, 1254, 1472, 2365, 1456, 2165, 1457, 2456, Second lowest value of the said array: 1456
