Hello,
I have two functions I often use to remove an element from a vector, and
it will be nice to add it directly in the vector module, or in the worst
case into a specific package. Cause I'm sure it will be useful and we
already have such functions for list, but not for vector...
; Remove the ith element of vector v
(define (vector-pop i v)
(vector-append (vector-copy v 0 i) (vector-copy v (+ i 1))))
; Like remove (from list) but for a vector
(define (vector-remove ele v)
(vector-filter-not (λ (x) (equal? x ele)) v))
Of course we have to use the check-vector/index to raise an error if "i"
is out of range (see vector.rkt).
