在 Julia 中获取数组的最后一个元素 – last() 方法
last()
是 julia 中的一个内置函数,用于返回指定可迭代集合的最后一个元素。
Syntax: last(coll)
Parameters:
- coll: Specified iterable collection.
Returns: It returns the last element of the specified iterable collection.
示例 1:
# Julia program to illustrate
# the use of last() method
# Getting the last element of
# the specified iterable collection
# or 1D array
println(last(1:2:3))
println(last(5:10))
println(last([3, 5, 7, 9]))
println(last([2, 4, 6, 8]))
输出:
3
10
9
8
示例 2:
# Julia program to illustrate
# the use of last() method
# Getting the last element of
# the specified 2D and 3D array
println(last([3 5; 7 9]))
println(last(["a" "b"; "c" "d"]))
println(last(cat([1 2; 3 4], [5 6; 7 8],
[2 2; 3 4], dims = 3)))
println(last(cat(["a" "b"; "c" "d"],
["e" "f"; "g" "h"],
["i" "j"; "k" "l"], dims = 3)))
输出:
