Playing with numbers: Missing numbersPlaying with numbers: Missing numbers Mercutio Thu, 2011-05-19 22:48
Let's say you have the following list of numbers:
1 2 4 7
And you want it to output the 'missing numbers' in between. Like so:
3 5 6
The first thing to look at would probably be setdiff(), a useful function that compares two lists, and
returns the values that were in one list, but not in the other.
Raevnos@M*U*S*H offers the following solution:
letq(D, firstof(%1, %b), setdiff(lnum(lmath(min, %0, %qD), lmath(max, %0, %qD), %qD), %0, %qD, n))
How would you do this?
