findIndices -package:rio

The findIndices function extends findIndex, by returning the indices of all elements satisfying the predicate, in ascending order.

Examples

>>> findIndices (`elem` "aeiou") "Hello World!"
[1,4,7]

>>> findIndices (\l -> length l > 3) ["a", "bcde", "fgh", "ijklmnop"]
[1,3]

O(n) The findIndices function extends findIndex, by returning the indices of all elements satisfying the predicate, in ascending order.

The findIndices function extends findIndex, by returning the indices of all elements satisfying the predicate, in ascending order.

O(n) The findIndices function extends findIndex, by returning the indices of all elements satisfying the predicate, in ascending order.

Outputs the indices of all elements that satisfied the predicate

The findIndices function extends findIndex, by returning the indices of all elements satisfying the predicate, in ascending order.

>>> findIndices (`elem` "aeiou") "Hello World!"
[1,4,7]

Stream all indices whose elements satisfy the given predicate

Find locations of non-overlapping instances of needle within haystack.

Returns the indices of all elements satisfying the function

Find all the indices where the element in the stream satisfies the given predicate.

O(n) The findIndices function extends findIndex, by returning the indices of all elements satisfying the predicate, in ascending order.

The findIndices function extends findIndex, by returning the indices of all elements satisfying the predicate, in ascending order. Beware: findIndices p xs will diverge if all the elements of any suffix of xs fails to satisfy p.

Returns the index of the latest element if the element satisfies the given predicate.

Find all the indices where the element in the stream satisfies the given predicate.

>>> findIndices p = Stream.scanMaybe (Fold.findIndices p)

O(n). Return the indices of all elements in a sorted list that satisfy the given condition.

Return indices of all elements, satisfying a predicate. This function isn't productive (e. g., head .' findIndices f won't terminate), if no elements of the input list satisfy the predicate.
