3021. Alice and Bob Playing Flower Game
Problem Explanation
Explanation
To solve this problem, we can iterate through all possible pairs of flowers in the clockwise and anti-clockwise directions and check if Alice can win the game based on those pairs. We can simulate the game for each pair and determine if Alice wins. If Alice wins, we increment the count of valid pairs. The simulation can be done by keeping track of the remaining flowers in each direction and the current player.
- Time Complexity: O(n * m), where n and m are the range limits for the number of flowers in each direction.
- Space Complexity: O(1)
Solution Code
class Solution {
public int numValidFlowerPairs(int n, int m) {
int count = 0;
for (int x = 1; x <= n; x++) {
for (int y = 1; y <= m; y++) {
if (canAliceWin(x, y)) {
count++;
}
}
}
return count;
}
private boolean canAliceWin(int x, int y) {
if (x == 1 && y == 1) {
return false;
}
return (x % 2 == 1) && (y % 2 == 0);
}
