Given an array of n integers, arr, make the values equal using the minimum number of operations.Minimum Cycles

Given an array of $n$ integers, arr, make the values equal using the minimum number of operations.

Either choose an element and apply the operation:

If the operation number is odd $($eg$.$ first, third, fifth,.$).,$ then increase the element by $1.$

If the operation number is even $($eg$.,$ second, fourth, sixth,..., then increase the element by $2.$

or do nothing.

Only one element can change in an operation.

Calculate the minimum number of operations required to make all elements equal.

Example

arr$=[1,2,4]$

$\backslash$table$[[\backslash$table$[[$Operation$],[$Number$]],$Operation type,$\backslash$table$[[$Resulting$],[$arr$]]],[1,\backslash$table$[[$Choose the $1^{st}$ element$],[$and add $1$since operation$],[$number is odd.$]],2,2,4$
