LC-1334. The city with the fewest neighbors within the threshold distance (Floyd algorithm, memorized search ==> dynamic programming (0x3f))

1334. The city with the fewest neighbors within the threshold distance medium There are n cities, numbered from 0 to n-1. Give you an edge array edges, where edges[i] = [fromi, toi, weighti] represents fromi and toi code> A bidirectional weighted edge between two cities, the distance threshold is an integer distanceThreshold. Returns the city […]

antd-vue + vue3 realizes the dynamic addition and deletion of rows in a-table, and implements in-row input verification in a-table through a-from

1. Renderings Figure 1: Verification effect 2. Main code Note: 1. The form and table are bound to the same data tableSource and it is a data (ElementUI requires an object package array) 2. The form uses name binding -> :name=”[index, ‘vlan_id’]” 3. Form-item always needs to add rules -> :rules=”rules.blur” <a-form ref=”tableFormRef” :model=”tableSource” :label-col=”{ […]
