886です。
ダメなんです。
BEGIN {
a[1] = 1;
a[2][1] = 21;
a[2][2] = 22;
a[3] = 3;
a[4][1][1] = 411;
a[4][2] = 42;
a[4][3][2][1] = 256;
for (i = 0; i < 9; i++) b[i] = i;
c["foo"]["corge"] = "grault";
c["foo"]["bar"] = "garply";
c["baz"]["corge"] = "waldo";
c["baz"]["quux"] = "fred";
print "length(a) = " length(a);
print "length(a) = " length(b);
print "length(a) = " length(c);
print "count_array(a) = " count_array(a);
print "count_array(b) = " count_array(b);
print "count_array(c) = " count_array(c);
}
length(a) = 4
length(b) = 9
length(c) = 2
count_array(a) = 7
count_array(b) = 9
count_array(c) = 4
再帰を使う以外に方法があれば、
と思い質問した次第です。
