A Slice of an array said to be a Bounded slice if Max(SliceArray)-Min(SliceArray)<=K. If Array [3,5,6,7,3] and K=2 provided .. the number of bounded slice is 9, first slice (0,0) in the array Min(0,0)=3 Max(0,0)=3 Max-Min<=K result 0<=2 so it is bounded sli...

leetcode 697[easy]---Degree of an Array 难度:easy Given a non-empty array of non-negative integers nums, the degree of this array is defined as the maximum frequency of any one of its elements. Your task is to find the smallest... ...
For every odd index i where 0 <= i < n / 2, assign the value of newNums[i] as max(nums[2 * i], nums[2 * i + 1]). Replace the array nums with newNums. Repeat the entire process starting from step 1. Return the last number that remains in nums after applying the algorithm...
Hello, I am trying some leetcode problems but couldnt solve it and had to look at the solution. But I am a bit confused with it. Mostly the 2 lines with INT_MAX and INT_MIN. I understand that these are the max and min that an int can be, but I just cant figure out how it ...
max - min $$max(a, b, c) min(a, b, c) = \frac{|a b| + |b c| + |c a|}{2}$$,两个也适用,n个也适用 算法 原创 暂为菊内人 2021-07-16 10:46:38 234阅读 Min Stack Design a stack that supports push, pop, top, and retrieving the minimum element in constant time....
If we consider the smallest max as a monotonic sequence, the lower bound of the sequence is the largest element in the array, and the higher bound is the sum of all elements. Then we choose the possible “smallest max” at the middle of the sequence and always greedily drops half of of...
