Type 'ty vector admits equality if 'ty does. Vectors v1 and v2 are equal if they have the same length and their elements are equal. [maxLen] is the maximal number of elements in a vector. [fromListxs] returns a vector whose elements are those of xs. Raises Size if length xs > maxLen. [tabulate(n, f)] returns a vector of length n whose elements are f 0, f 1, ..., f (n-1), created from left to right. Raises Size if n<0 or n>maxLen. [lengthv] returns the number of elements in v. [sub(v, i)] returns the i'th element of v, counting from 0. Raises Subscript if i<0 or i>=length v. [update(v, i, x)] creates a copy of v, sets position i to x, and returns the new vector. In contrast to Array.update, this is not a constant-time operation, because it must copy the entire vector. Raises Subscript if i<0 or i>=length v. [concatvs] returns a vector which is the concatenation from left to right og the vectors in vs. Raises Size if the sum of the sizes of the vectors in vs is larger than maxLen. [findp v] applies p to each element x of v, from left to right, until p(x) evaluates to true; returns SOME x if such an x exists, otherwise NONE. [existsp v] applies p to each element x of v, from left to right, until p(x) evaluates to true; returns true if such an x exists, otherwise false. [allp v] applies p to each element x of v, from left to right, until p(x) evaluates to false; returns false if such an x exists, otherwise true. [foldlf e v] folds function f over v from left to right. That is, computes f(v[len-1], f(v[len-2], ..., f(v[1], f(v[0], e)) ...)), where len is the length of v. [foldrf e v] folds function f over v from right to left. That is, computes f(v[0], f(v[1], ..., f(v[len-2], f(v[len-1], e)) ...)), where len is the length of v. [appf v] applies f to v[j] for j=0,1,...,length v-1. [mapf v] applies f to v[j] for j=0,1,...,length v-1 and returns a new vector containing the results. The following iterators generalize the above ones by passing also the vector element index j to the function being iterated. [findip a] applies f to successive pairs (j, a[j]) for j=0,1,...,n-1, until p(j, a[j]) evaluates to true; returns SOME (j, a[j]) if such a pair exists, otherwise NONE. [foldlif e v] folds function f over the vector from left to right. That is, computes f(n-1, v[n-1], f(..., f(1, v[1], f(0, v[0], e)) ...)) where n = length v. [foldrif e v] folds function f over the vector from right to left. That is, computes f(0, v[0], f(1, v[1], ..., f(n-1, v[n-1], e) ...)) where n = length v. [appif v] applies f to successive pairs (j, v[j]) for j=0,1,...,n-1 where n = length v. [mapif v] applies f to successive pairs (j, v[j]) for j=0,1,...,n-1 where n = length v and returns a new vector containing the results. [collatecmp (xs, ys)] returns LESS, EQUAL or GREATER according as xs precedes, equals or follows ys in the lexicographic ordering on vectors induced by the ordering cmp on elements. *)
