"use strict";

process.stdin.resume();
process.stdin.setEncoding("utf-8");

let ​inputString = "";
let ​currentLine = 0;

process.stdin.on("data", (inputStdin) => { ​inputString += inputStdin;
});

process.stdin.on("end", (_) => { ​inputString = inputString.trim().split("\n").map((str) => str.trim()); ​main();
});

function readLine() { ​return inputString[currentLine++];
}
/* Please do not modify anything above this line */

function main() { ​const nestedArray = JSON.parse(readLine()); ​/* Write your code here */
 ​const resultArray = nestedArray.map(arr => { ​if ( arr.some(item => item % 2 === 0) ) { ​return arr.reduce( (acc, current) => acc * current ) ​} else { ​return 0 ​} ​});
 ​console.log(resultArray);
