Oct 5, 2017 at 15:21	comment	added	Kevin Cruijssen		Same change I suggested to save 1 byte regarding -1/+1 of `j` and `x` still applies to your latest edit: `b=>a=>{m=[];x=a.length;y=b.length+1;for(i=y;i--;)m[i]=[[i,'R'.repeat(i)]];for(j=x+1;j--;)m[i=0][j]=[j,'A'.repeat(j)];for(;++i<y;)for(j=-1;++j<x;)R=m[S=(X=m[i-1][j])[0],I=(Y=m[i][j])[0],D=(Z=m[i-1][j+1])[0],Q=[D+1,Z[1]+'R'],i][j+1]=b[i-1]==a[j]?[S,X[1]+' ']:S<I?D<S?Q:[S+1,X[1]+'M']:D<I?Q:[I+1,Y[1]+'A'];return[(g=s=>R[1].replace(/./g,c=>c==s?' ':b[i++],i=0))('A'),g('R',b=a),R[1]]}` :)
