Title:Given an array of non-negative integers, you is initially positioned at the first index of the array.Each element of the array represents your maximum jump length is at that position.Your goal is to reach the last index in the minimum number of jumps.for example:given array A =[2,3,1,1,4] the minimum number of jumps to reach the last index Is2 . (Jump1 step from index 0 to 1, then3 steps to the last index.) idea: This topic is similar to the jump game mentality. Only this time, we have

The network access control optimization solution is worth exploring. Many people may not know about network access control yet. It does not matter. After reading this article, you must have gained a lot, I hope this article will teach you more things. Network Access Control Based on hardware, software network access control based on proxy, software network access control without proxy, or dynamic network access control can all improve network security. To select the right solution, IT managers n

How to set the optimal 4G memory virtual memory ?, 4G memory virtual memory Memory is one of the important components in the computer and serves as a bridge to communicate with the CPU. So, do you know how much virtual memory should be set for the 4g memory of the W7 system? Within 4 GB of physical memory, the virtual memory is generally set to 2 times of physical memory, for example, 1 GB of physical memory is set to 2 GB of virtual memory. In thi

MySQL 5.6 5.7 optimal configuration file template (my. ini), mysql5.6 Inside has compiled a new configuration file template based on MySQL 5.6 and 5.7, which basically covers 90% of the optimization options. You only need to make slight modifications based on your server configuration, for example, InnoDB buffer pool size and IO capacity (innodb_buffer_pool_size, innodb_io_capacity ). Note that this configuration file does not need to be modified. Yo
