1、题目描述
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。
2、代码实现
import java.util.ArrayList;
public class Solution {
public int[] multiply(int[] A) {
int length = A.length;
int[] B = new int[length];
for (int i = 0; i < length; i++) {
int sum = 1;
for (int j = 0; j < length; j++) {
if (j == i) {
continue;
}
sum = sum * A[j];
}
B[i] = sum;
}
return B;
}
}
