Given an array, return the minimum number of operations required to make all the elements of the array continuous. In one operation, any element of the array can be replaced with any integer.

Example

For arr $=[6,4,1,7,10],$ the output should be solution$($arr$)=2.$

In this example, the minimum number of operations needed to make all the elements of the array continuous is $2.$ You could replace $1$ with $5$ and $10$ with $8$ so that array will become arr $=[6,4,5,7,8]$ which has continuous elelements.
