矢量被定义为具有三个维度,由三个数字的有序集合表示:(X,Y,Z)。
任务:
Write a function that takes any numbers of vectors (arrays) as input and computes their dot product.
您的函数应在无效输入(即不同长度的向量)上返回null
。
dotProduct(...nVectors)
应该返回dotProduct(...nVectors)
testString: 'assert.equal(dotProduct([ 0, 1, 2, 3, 4 ], [ 0, 2, 4, 6, 8 ], [ 0, 3, 6, 9, 12 ], [ 0, 4, 8, 12, 16 ], [ 0, 5, 10, 15, 20 ]), 156000, "dotProduct(...nVectors)
should return 156000");'
