# The zero array

**Computer Science**Level 4

Given a zero-array (containing only 0's), it is desired to converting it to a certain target array of the same size, and only the following operations are allowed:

**Increment**: Choose an element from the array and increment it by 1.

**Doubling**: Double the value of every element on the array

What is the minimum number of operations required to convert a zero-array to the target array shown in the text file?

**Details and Assumptions**:

For a target array \([2, 2, 3]\) the minimum number of operations is 5.

`[0,0,0] -> [1,0,0] -> [1,1,0] -> [1,1,1] -> [2, 2, 2] -> [2, 2, 3]`
