使用一个字典保存数组某个位置之前的数组和,然后遍历数组求和,这样当我们求到一个位置的和的时候,向前找sum-k是否在数组中,如果在的话,更新结果为之前的结果+1。同时,当前这个sum出现的次数就多了一次。 和560. Subarray Sum Equals K几乎一模一样的题目,为什么就是不会做呢? classSolution(object):defnumSubarr...

In its current form, the GAM learner has the following advantages and disadvantages: on the one hand, they offer ready interpretability combined with expressive power, but on the other, they are currently slow. We would recommend their usage in the case where the key criteria is interpretability...
so now we need to check whether there is a subarray of a new array ai−λ of length at least x+1 with non-negative sum, which is doable with some prefix sums.Continuous search¶Let f:R→R be a real-valued function that is continuous on a ...
We derive a large set of binary operations that are algebraically isomorphic to the binary operation of the Beltrami–Klein ball model of hyperbolic geometry, known as the Einstein addition. We prove that each of these operations gives rise to a gyrocomm
Binary sequences are algebraic structures currently used as security elements in Internet of Things devices, sensor networks, e-commerce, and cryptography. In this work, a contribution to the evaluation of such sequences is introduced. In fact, we presen
A Zero-Sum Game Every binary option expires at $100 or $0: $100 if the proposition is true and $0 if false. Each thus has a total value potential of $100, and it's azero-sum game. When you profit, someone loses, and when you lose, someone profits. ...
