One, flatten an arrayA problem encountered a few days ago, there is an array of Var str=[1,2,1,[4,5,[6,7,[8,9]]]; How to say this array is flattened, removing these repeating brackets. I also think for a long time to write out, here to share to you. 1 varstr=[1,2,1,[4,5,[6,7,[8,9]]]];2 functionarr (str,depth) {//depth represents the number of flattening3

Sometimes, we run into situations where I end up with a maybe within the context of another maybe. Nested structures like this can get really confusing to work with. In this lesson, we'll look at a example of this and see how can help us off by chain flattening the nestedMaybeAs we all know, inside a array return another array is nested array.Inside observable return another observable get observable of obs

[Copy question]:Given a nested list of integers, implement an iterator to flatten it.Each element was either an integer, or a list--whose elements may also be integers or other lists.Example 1:Given the list [[1,1],2,[1,1]] ,By calling next repeatedly until hasnext returns FALSE, the order of elements returned by next should be: [1,1,2,1,1] .Example 2:Given the list [1,[4,[6]]] ,By calling next repeatedly until hasnext returns FALSE, the order of elem
Implement a iterator to flatten a 2d vector.For example, Given 2d vector =[ [1,2], [3], [4,5,6]] By calling next repeatedly until Hasnext returns false, the order of elements returned by next should is: [1,2,3,4,5,6] .Analysis: 1190000003791233An array is used to represent the iterator for each list, and then a variable is recorded to indicate that the first iterator is currently used.1 Public classvect
