I have a vector of values

 

X = seq(1:10)

 

I want to get another vector V of with sample (with replacement) of X but
with a constrain:  V will have as much elements as those necessary to V sum
exactly 10.

 

If the N-th value of V make the sum greater than 10, it's is subtracted with
the difference to achieve the constrain.

 

I don't know how to achieve this. with a while?
