Hello everyone,
Not sure how to do this using Map, or even if it's possible.
I can compare a target value to each value in a list like this.
targetX = 5; listX = {4, 9, 2, 11, 4};
targetX > # & /@ listX
{True, False, True, False, True}
I can do the same for another target and another list.
targetY = 3; listY = {4, 0, 1, 8, 6};
targetY > # & /@ listY
{False, True, True, False, False}
But can I do it in a similar way for the AND or OR condition without
having to resort to the Table command?
Table[targetX > listX[[i]] && targetY > listY[[i]], {i, Length@listX}]
{False, False, True, False, False}
Table[targetX > listX[[i]] || targetY > listY[[i]], {i, Length@listX}]
{True, True, True, False, True}
Much obliged,
Gregory
