Enumerating and eliminating |
Could you please help me to enumerate and eliminate elements of a set? For example, from a loop: for(k=1,10,x=k+3;if(x<10,print(x," ",k))) I get the result: 4 1 5 2 6 3 7 4 8 5 9 6 And I want to enumerate the values of x as x[1]=4,....,x[6]=9. Another example: for(k=1,5,if(k<3,y=k,y=k-2);print(y)) and the result: 1 2 1 2 3 Here I have 2 values of y are repeated (1 and 2) and I would like to eliminate them and write a set A={value of y}={1,2,3} and then enumerate the values of y as y[1]=1,y[2]=2,y[3]=3... However, I do not know how to do this @@. I wonder if there is someone help me solve it? Thank you so much. Phuong Ha.
