构建乘积数组

给定一个数组A[0,1,...,n-1],请构建一个数组B[0,1,...,n-1],其中B中的元素B[i]=A[0]A[1]...A[i-1]A[i+1]...A[n-1]。不能使用除法。

  function multiply(array) {
    let B = []
    let change = false
    for (let i = 0; i < array.length; i++) {
      B[i] = 1
      for (let j = 0; j < array.length; j++) {
        let temp = 1
        if (i === j) {
          change = true
          temp = array[j]
          array[j] = 1
        }
        B[i] *= array[j]
        if (change) {
          array[j] = temp
          change = false
        }
      }
    }
    return B
  }

  console.log(multiply([1,2,3,4,5]))
