reverse

reverse(X)

X is a vector/matrix/in-memory table/ordered dictionary.

• If X is a vector or matrix, return a new vector or matrix with reverse order of the original vector or matrix.
• If X is an ​​in-memory table​, return an in-memory table with reverse ​​row order.
• If X is an ​​ordered dictionary, return an ordered dictionary where the ​​key-value pairs are in reverse order.

reverse `hello `world;
// output: [world,hello]

(1..6).reverse();
// output: [6,5,4,3,2,1]

x=1..6$2:3;
x

reverse(x);

t = table(1 2 3 as a, `x`y`z as b)
reverse(t)

d = dict(1 2 3, `x`y`z, true)
reverse(d)

/*
output:
3->z
2->y
1->x
