next() // 放行的意思 } 但是在看别的项目时常常能看到next('/logon') 、 next(to) 或者 next({ ...to, replace: true }) 这又是啥意思呢...其实在路由守卫中,只有next()是放行,其他的诸如:next('/logon') 、 next(to) 或者 n...
官方思路(与下方相同):https://leetcode-cn.com/problems/next-permutation/solution/ http://fisherlei.blogspot.com/2012/12/leetcode-next-permutation.html 图中文字翻译: 从右向左,找到第一个违反生序的,也就是图中的6,叫他‘partitionnumber’。
