QUESTION
Given an array arr[ ] of n integers, construct a Product Array prod[ ] (of same size) such that prod[i] is equal to the product of all the elements of arr[ ] except arr[i].\n\nInput:\n\nThe first line of input contains an integer T denoting the number of test cases.\nThe first line of each test case is N,N is the size of array.\nThe second line of each test case contains N input A[i].\n\nOutput:\n\nPrint the Product array prod[ ].\n\nConstraints:\n\n1<=T<=10\n1<=N<=15\n1<=C[i]<=20.
“TESTCASE_1”: “2\n5\n10 3 5 6 2\n2\n12 20\n###—###SEPERATOR—###—\n180 600 360 300 900 \n20 12 “, “TESTCASE_2”: “2\n5\n1 4 7 9 8\n2\n1 2\n###—###SEPERATOR—###—\n2016 504 288 224 252 \n2 1 “, “TESTCASE_3”: “0\n###—###SEPERATOR—###—\n0”, “TESTCASE_4”: “0\n###—###SEPERATOR—###—\n0”, “TESTCASE_5”: “0\n###—###SEPERATOR—###—\n0
ANSWER
#include <iostream>
using namespace std;
int main()
{int t;
cin>>t;while(t--){
int n,i,prod=1;
cin>>n;
int a[n];
for(i=0;i<n;i++){
cin>>a[i];
prod*=a[i];
}
for(i=0;i<n;i++){
cout<<prod/a[i]<<" ";}cout<<endl;}
return 0;
}
