반응형 Count1 python count built-in function example Given a non-empty 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?Example 1:Input: [2,2,1] Output: 1 Example 2:Input: [4,1,2,1,2] Output: 4 Brute-force way => comparing every elements while loop. However, if we use count function we can solve this pro.. 2019. 1. 15. 이전 1 다음 반응형
