It is known that there are 46 students in the class, 35 of them like playing basketball, 35 of them like playing football, 38 of them like swimming, and 40 of them like table tennis. At least how many people participate in all four sports? (Sports are different from the original title)
已知全班共有46人，有35人喜欢打篮球，还有35人喜欢踢足球，还有38人喜欢游泳，还有40人喜欢乒乓球，问四种运动都参加的至少有多少人？(体育项目与原题有出入)
