Problem $1.$

Write a code as follows:

Create three arrays A$,$ B$,$ and C of each size $10.$

A$,$ B$,$ and C should have all distinct random numbers between $1$ and

$15$ inclusively $($use lab$15,$ problem $2).$

Write a function called findCommonInThree that finds the numbers

that are common in $A,B$ and $C.$

Do not modify main function.

You should complete three functions $-$ fillArray, printArray and

findCommonInThree.
