CF1296A Array with Odd Sum 前置芝士: 简单的位运算知识:x & 1 == 1 则x 是奇数,否则是偶数。 小奥奇偶性: ABA+B 奇数 奇数 偶数 奇数 偶数 奇数 偶数 偶数 偶数 思路 分类讨论: 都是偶数:NO 任意操作后数列的每个数都仍然是偶数,和也是偶数。 都是奇数:这个不好判断。 奇数个奇数加起来是奇数...
Your task is to say if it is possible to obtain an array with an odd (not divisible by22 ) sum of elements. You have to answertt independent test cases. Input The first line of the input contains one integertt (1≤t≤20001≤t≤2000 ) — the number of test cases. The next2t2t l...

您可以使用更新的偶数/奇数属性返回一个新对象,以便acc在所有迭代过程中保持为对象: const nums = [1,2,3,4,5,6,7,8,9]; function getOddEven(numbers){ return numbers.reduce((acc, cuu) => cuu % 2 === 0 ? {odd: acc.odd, even: acc.even + cuu} : {even: acc.even, odd: acc.odd...

be careful with the above function "array_delete"'s use of the stristr function, it could be slightly misleading. consider the following: <?php function array_delete($array, $filterforsubstring){ $thisarray = array (); foreach($array as $value) if(stristr($value, $filterforsubstring)=...
