Software

bugs and mistakes I always make

for sorting

const conres =
  { variety: 'Glacier', dot: 'yellow', num: 0 },
  { variety: 'Supersweet 100', dot: 'blue', num: 0 },
  { variety: 'Brandywine', dot: 'red', num: '5' },
  { variety: 'Purple Cherokee', dot: 'purple', num: '7' },
  { variety: 'Moskovich', dot: 'green', num: '4' },
  { variety: 'Valencia', dot: 'orange', num: '4' },
  { variety: 'Striped German', dot: 'pink', num: '4' },
  { variety: 'Glacier', dot: 'yellow', num: '4' },
  { variety: 'Supersweet 100', dot: 'blue', num: '4' },

const sorres =conres.sort((a,b)=>a.variety < b.variety ? -1 :1)

NOT

const sorres =conres.sort((a,b)=>a.variety < b.variety)

basic routines that I should know

You should implement the most common data structures in your language of choice. Do not rely on common libraries. Implement the following and write tests for them:

• vector (dynamic array),
• linked list,
• stack,
• queue,
• circular queue,
• hash map,
• set,
• priority queue,
• binary search tree
