intersection

问题 When optional and required property are merged via intersection, required wins type A = { who: string } type B = { who?: string } // $ExpectType {who:string} type R = A & B This may lead to runtime errors, when for instance, dealing with default params pattern within a function type Params = { who: string greeting: string } const defaults: Params = { greeting: 'Hello', who: 'Johny 5', } function greeting(params: Partial<Params>){ // $ExpectType Params const merged = {...defaults, ...params}

问题 I was wondering if a solution exists in pure CSS to color the intersection between two divs. For exemple, if I have two divs, with the same class like this: <div class="orange_square"></div> <div class="blue_square"></div> They are placed on the page so they so they overlap, like this: I want the intersection of these two divs to be colored in red, and this in CSS only. I was wondering if something like this existed: .orange_square { background-color:orange; } .blue_square { background-color

问题 I want to build the intersection of two python sets, but i need to have a custom equality to do this. Is there a way to specify "equaliy" directly when doing the intersection? For example due to a lambda-expressions? I know there is way by overriding eq , but i have to do several intersections on the same classes with different "equalities". Thanks! 回答1: Preface What you are trying to do makes perfect mathematical sense by using the right terms. The "equalities" you are referring to are

问题 I have set of line segments (not lines) , (A1, B1) , (A2, B2) , (A3, B3) , where A , B are ending points of the line segment. Each A and B has (x,y) coordinates. QUESTION: I need to know the shortest distance between point O and line segments as shown in the shown figure implemented in line of codes. The code I can really understand is either pseudo-code or Python. CODE: I tried to solve the problem with this code, unfortunately, it does not work properly. def dist(A, B, O): A_ = complex(*A)

问题 I am not that experienced in python but improving it thanks to this community! I desperately need a function which takes the input and gives the ouput below: Input : 1- Latitude/longitude coordinates of the center of circle 1 (e.g. (50.851295, 5.667969) ) 2- The radius of circle 1 in meters (e.g. 200) 3- Latitude/longitude coordinates of the center of circle 2 (e.g. (50.844101, 5.725889) ) 4- The radius of circle 2 in meters (e.g. 300) Output : Possible output examples can be; The
