I still try to solve this task (this task).I’ve corrected my previous code
public class Main {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int t = scanner.nextInt();
for (int testCase = 0; testCase < t; testCase++) {
int n = scanner.nextInt();
int[] heights = new int[n];
for (int i = 0; i < n; i++) {
heights[i] = scanner.nextInt();
}
int maxCount = 0;
int maxHeight = 0;
int countZeros = 0;
int minHeight = heights[0];
for (int height : heights) {
if (height < minHeight) {
minHeight = height;
}
if (height == 0) {
countZeros++;
}
if (height > maxHeight) {
maxHeight = height;
maxCount = 1;
} else if (height == maxHeight) {
maxCount++;
}
}
if (heights.length == 1 && maxHeight != 0) {
System.out.println(1);
continue;
}
if (maxHeight == 0 || maxCount % 2 == 0) {
System.out.println(0);
continue;
}
if (maxCount == 1 && countZeros > 0) {
System.out.println(1);
continue;
}
if (maxCount == 1 && n % 2 != 0) {
System.out.println(minHeight);
continue;
}
if (maxCount > 1 && maxHeight == 1) {
System.out.println(maxCount);
} else if (maxCount > 1) {
System.out.println(maxCount * maxHeight);
} else {
System.out.println(1);
}
}
scanner.close();
}
}
He passes my tests such as:
#1
Input:
1
6
4 4 4 4 4 2
Output:
20
#2
Input:
1
5
1 0 1 0 1
Output:
3
#3
Input:
1
4
10 4 4 4
Output:
1
#4
Input:
1
3
3 3 3
Output:
9
#5
Input:
1
4
10 10 10 10
Output:
0
#6
Input:
1
3
4 3 3
Output:
3
In test 1 we get 20 because we can take the first move away from all 5 of the highest fours (1,2,3,4) and so we multiply 4 by 5.
but I still don’t understand what’s wrong and have WA.((
