@*Intro. A triviality to put the Flammenkamp--Clift table of addition
chain data into the format of my {\mc ACHAIN} programs.

@c
#include <stdio.h>
main()
{
  register int c,h,i,j,k,n;
  for (n=1,h=0;;n++) {
    if (!h) {
      c=fgetc(stdin);
      if (c==EOF) break;
      h=3;
    }@+else h--,c>>=2;
    for (i=j=0,k=n;k;k>>=1,j++) i+=k&1;
    for (i--;i;j++) i>>=1;
    putchar((c&3)+j+(' '-1));
  }
}

@*Index.
