【Leetcode】Day1 Singular number
開個貼記錄leetcode刷題,每天刷三道easy兩道medium,用python和c++做。今天第一天,加油!
【題目】:
原題:Given an array of integers, every element appears twice except for one. Find that single one.
Note:
Your algorithm should have a linear runtime complexity. Could you implement it without using extra memory?
翻譯:給定一個數組,裏面全是整數,每個數字都重復兩遍,只有一個沒有重復,找到那個不重復的數字。
註意:時間復雜度為線性,並且不占用額外內存。
