The Sum ofGiven an array of integers, find the numbers such that they add up to a specific target number.The function twosum should return indices of the numbers such that they add up to the target, where index1 must is Les S than Index2. Please note that your returned answers (both Index1 and INDEX2) is not zero-based.You may assume this each input would has exactly one solution.Input: numbers={2, 7, one, target=9Output: index1=1, index2=2Test instru

single-block mechanical disk available on the market now has only 10TB of storage space. When this part of the capacity is used to expand it is basically an impossible task to complete. Finally this storage method also has the security question, the single piece mechanical disk in the continuous high I/O environment is very easy to damage, as long as is a certain capital support company, the mechanical disk itself is regarded as the consumable.So even in a start-up company's online production e
