Question Given an unsorted integer array, find the first missing positive integer. For example,Given[1,2,0]Return3,And[3,4,-1,1]Return2. Your algorithm shocould run in O (n) time and uses constant space. Method When switching A [I] to A [A [I]

Question: N, T, S, E: give you T edge. Each edge has a number and a weight. From S to E, N edges are allowed, find the shortest path. The idea of foyld's rapid power of matrix addition. Note that edge discretization is required. #include

This is the simplest question about backpacks. This question should be a test point except for a backpack: Two-dimensional arrays cannot be opened. I haven't opened a two-dimensional architecture, but it's impossible to read data. It's too

  Question: n number series. The number of occurrences of the number k in a certain interval in m queries. N, m   Solution: because it is offline, it can be processed in a unified manner before being output. You can maintain a left and right

Binary Search Algorithm Question: Set a [0: n-1] to an array in sorted order. Rewrite the binary search algorithm so that when the search element x is not in the array, return the position I of the largest element smaller than x and the position j
