💡 Hint

Common Mistakes

Using commas which are not valid operators here.

Using + without spaces causing numbers to join without spaces.

Adding a space string between numbers concatenates them with spaces.

5fill in blank

hard

Fill all three blanks to print "Sum: 15" on a new line using variables.

Kotlin

val a = 7
val b = 8
println([1] + ([2] + [3]))

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Putting variables before the string causing wrong output.

Using the string "15" instead of adding variables.

Concatenate the string "Sum: " with variables a and b to print the sum.
