My HOC :

```
const withPaper = Component => props => (
<Paper>
<Component {...props} />
</Paper>
);
export default withPaper;
```

I want to style ‘Paper’ component using withStyles() :

Code is a question and answer site for professional and enthusiast programmers.

I have an array of objects, something like this:

```
const data = [ // array1
[{x: 1}, {y:2}, {z:3}],
[{x: 1}, {y:2}, {z:3}],
[{x: 1}, {y:2}, {z:3}]
],[ // array2
[{x: 1}, {y:2}, {z:3}],
[{x: 1}, {y:2}, {z:3}],
[{x: 1}, {y:2}, {z:3}]
]
```

What needs to be accomplished is summing `x`

from the `array1`

with `x`

from the `array2`

that have the same index. Same goes for `y`

and `z`

. The final result should be a new array of objects containing the summed values.

Something like this:

```
[
[{totalXOne: 2}, {totalYOne: 4}, {totalZOne: 6}],
[{totalXTwo: 2}, {totalYTwo: 4}, {totalZTwo: 6}],
[{totalXThree: 2}, {totalYthree: 4}, {totalZThree: 6}],
]
```

**Note:** All arrays are the same length, and if a value is missing it will be replaced with `0`

)

I found something nice on MDN, but it’s summing all `x`

, `y`

, `z`

values, and it’s returning single summed values, like this:

```
let initialValue = 0;
let sum = [{x: 1}, {x:2}, {x:3}].reduce(function(accumulator,currentValue) {
return accumulator + currentValue.x;
}, initialValue)
```

I have lookup expression to compare two datasets, the lookup is missing certain rows. Some rows in Totaldownload in DataSetCount have value of that data , but lookup is skipping. Some rows are lookup correctly why some were skipped. I am not sure if anyone has encountered this problem before where lookup is just returning blank to some rows in the column. please see image below ….

I have to find a php code to solve a math problem.

A and B are playing a game of stones. A start always the game.

They will pick in turns 2 consecutive stones from a line until there are no consecutive stones –> condition1: stone i and stone i+1, where 1 ≤ i ≤ N−1

The line has N stones and are indexed from 1 to N. Condition2: N (1 ≤ N ≤ 10 000 000)
