Some Thoughts Poor BASIC people... | Comment 8 of 32 |
...who have to write so much code for such a little problem! In Linux you can use AWK as follows:
   BEGIN {

for (A=0; A<=9; A++) {
for (B=0; B<=9; B++) {
for (C=0; C<=9; C++) {
for (D=0; D<=9; D++) {
ABCD1 = A B C D \"\"
ABCD2 = (A^B)*(C^D)
if (ABCD1+0)=ABCD2) print ABCD
}
}
}
}
}
