题解：

bool canPartition(int* nums, int numsSize) {if (numsSize < 2) {return false;}int sum = 0, maxNum = 0;for (int i = 0; i < numsSize; ++i) {sum += nums[i];maxNum = fmax(maxNum, nums[i]);}if (sum & 1) {return false;}int target = sum / 2;if (maxNum > target) {return false;}int dp[target + 1];memset(dp, 0, sizeof(dp));dp[0] = true;for (int i = 0; i < numsSize; i++) {int num = nums[i];for (int j = target; j >= num; --j) {dp[j] |= dp[j - num];}}return dp[target];
}
