A weekly Monde current mathematical puzzle that reminded me of an earlier one (but was too lazy to check):

If ADULE-ELUDE=POINT, was is the largest possible value of POINT? With the convention that all letters correspond to different digits and no digit can start with 0. Same question when ADULE+ELUDE=POINT.

The run of a brute force R search return 65934 as the solution (codegolf welcomed!)

```dify<-function(aluda,point)
(sum(aluda*10^(4:0))-sum(rev(aluda)*10^(4:0)))
num2dig<-function(dif) (dif%/%10^(0:4))%%10
sl=NULL
for (t in 1:1e6){
sl=as.matrix(distinct(as.data.frame(sl),.keep_all = TRUE))
```

where distinct is a dplyr R function.

```> 94581-18549
[1] 76032
```

The code can be easily turned into solving the second question

```> 31782+28713
[1] 60495
```
