-/**
- * Compares all values of two observables in sequence using an optional comparator function
- * and returns an observable of a single boolean value representing whether or not the two sequences
- * are equal.
- *
- * <span class="informal">Checks to see of all values emitted by both observables are equal, in order.</span>
- *
- * ![](sequenceEqual.png)
- *
- * `sequenceEqual` subscribes to two observables and buffers incoming values from each observable. Whenever either
- * observable emits a value, the value is buffered and the buffers are shifted and compared from the bottom
- * up; If any value pair doesn't match, the returned observable will emit `false` and complete. If one of the
- * observables completes, the operator will wait for the other observable to complete; If the other
- * observable emits before completing, the returned observable will emit `false` and complete. If one observable never
- * completes or emits after the other complets, the returned observable will never complete.
- *
- * ## Example
- * figure out if the Konami code matches
- * ```javascript
- * import { from, fromEvent } from 'rxjs';
- * import { sequenceEqual, bufferCount, mergeMap, map } from 'rxjs/operators';
- *
- * const codes = from([
- *   'ArrowUp',
- *   'ArrowUp',
- *   'ArrowDown',
- *   'ArrowDown',
- *   'ArrowLeft',
- *   'ArrowRight',
- *   'ArrowLeft',
- *   'ArrowRight',
- *   'KeyB',
- *   'KeyA',
- *   'Enter', // no start key, clearly.
- * ]);
- *
- * const keys = fromEvent(document, 'keyup').pipe(map(e => e.code));
- * const matches = keys.pipe(
- *   bufferCount(11, 1),
- *   mergeMap(
- *     last11 => from(last11).pipe(sequenceEqual(codes)),
- *   ),
- * );
- * matches.subscribe(matched => console.log('Successful cheat at Contra? ', matched));
- * ```
