Hey there! Welcome to ClearUrDoubt.com. In this post, we will look at a Scala program to separate even and odd numbers in a List of Integers. We can achieve this using “partition” function defined on List. partition function takes a predicate Read more
Hey there! Welcome to ClearUrDoubt.com. In this post, we will look at a Scala program to convert an Array into an instance of Map. Let’s look at the program:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
object ArrayToMap extends App { val ints = Array(1, 2, 3, 4) val strings = Array("ONE", "TWO", "THREE", "FOUR") //Convert above ints and strings arrays into a Map val mapIntToStrings = (ints zip strings).toMap println("Int to String Map = " + mapIntToStrings.mkString(", ")) //Convert above ints and corresponding indices into a Map val mapIntsToIndices = (ints zipWithIndex).toMap println("Int to Index Map = " + mapIntsToIndices.mkString(", ")) } |

Hey there! Welcome to ClearUrDoubt.com. In this post, we will look at a Scala program to find the largest number in a given list of integers using reduceLeft. Let’s look at the program:

package com.clearurdoubt.practice object FindMax extends App { val l = List(1,-5,10,3,9) val max = l.reduceLeft( (a, b) => if(a > b) a else b ) println("Maximum number in (1,-5,10,3,9): " + max) } |
