Your question is Greedy Mobile Grid Layout. Start with the requirements on the right.
Run and submit as often as you like. When you're ready, talk me through your approach or go straight to the code.
At PixelFlow, a mobile screen must display identical rectangular cards in a grid. Write a function that calculates the optimal layout for a given screen width, card minimum width, gap size, and number of cards.
The goal is to place as many columns as possible while ensuring each card is at least min_card_width pixels wide. Among all valid layouts, choose the one with the maximum number of columns. Then compute the resulting card width and the number of rows needed.
Implement a function that receives:
screen_width: integer total width of the screen in pixelsmin_card_width: integer minimum allowed width for each cardgap: integer horizontal gap between adjacent cardsitem_count: integer number of cards to placeReturn a list [columns, card_width, rows] where:
columns is the chosen number of columnscard_width is the integer width of each card after distributing available space evenlyrows is the number of rows required to place all cardsIf item_count is 0, return [0, 0, 0].
