Not having used Mathematica for months, I have forgotten some of the little I knew.
I have a list of lists like this:
test = { {{4, 5}, {5, 9}, {6, 2}},
{{2, 3}, {3, 5}},
{{7,1}, {9, 8}, {0, 7}, {2, 8}},
{{4, 3}, {6, 5}}};
test // ColumnForm
{{{4, 5}, {5, 9}, {6, 2}},
{{2, 3}, {3, 5}},
{{7, 1}, {9, 8}, {0, 7}, {2, 8}},
{{4, 3}, {6, 5}}}
What I want to do is just remove the last element in each sublist, with this result:
{{{4, 5}, {5, 9}},
{{2, 3}},
{{7, 1}, {9, 8}, {0, 7}},
{{4, 3}}}
There must be some simple functional way to do this, but I haven't found it.
I will appreciate any tips. Thank you.
