Leetcode 暑期bb班

係咪temp_max 唔洗加個0落去？

早兩個月揾工俾人問曲問到口啞
家陣操完leetcode 就含理論野

Review Last 2 problems:
https://leetcode.com/problems/sorting-the-sentence/
呢題主要考string comprehension



https://leetcode.com/problems/how-many-numbers-are-smaller-than-the-current-number/
呢題有兩個做法，純sort or 用dict
我地用純sort

今日兩題（唔記得day 幾，好似day 9）
https://leetcode.com/problems/sort-integers-by-the-number-of-1-bits/
呢題主要係考要識binary representation

https://leetcode.com/problems/rank-transform-of-an-array/
呢題同上次果條smaller element好似，當溫習下

聽日見

香港搵工要識埋啲lang domain knowledge，好難
我之後如果返香港都要向你地請教

你可以睇下kadane係咩
同你個concept差唔多，不過寫得短啲啲
你唔知kadane自己做到都好勁啦

睇咗了，好精彩

Two new problems:
https://leetcode.com/problems/find-k-closest-elements/
https://leetcode.com/problems/custom-sort-string/

Q1: sort by (num.bit_count(), num)?
Q2: sorted(range(len(arr)), key=lambda i: arr[i]) 或者 {v: r for r, v in enumerate(sorted(set(arr)), 1)} 之後執返啲 rank?

yes

我連第二題都唔識做係咪 min {f(n) : n = a node of layer's n} = min( f(n-1) + 個node+線嘅value}咁?
