Lesson 5-3 - MinAvgTwoSlice 내용 : Find the minimal average of any slice containing at least two elements. 시간 복잡도 : O(n) 정답 코드는 : def solution(A): min_avg_value = (A[0] + A[1])/2.0 # The mininal average min_avg_pos = 0 # The begin position of the first # slice with mininal average for index in xrange(0, len(A)-2): # Try the next 2-element slice if (A[index] + A[index+1]) / 2.0
