方法:动态规划,定义二维数组coins,coinsa表示把第a个气球和第b个气球之间(不包括a和b)的气球戳烂,最大能得到的分值
代码语言:javascript复制public class Solution {
public int maxCoins(int[] nums) {
int[] dpnums = new int[nums.length 2];
dpnums[0] = 1;
dpnums[dpnums.length - 1] = 1;
for(int i = 0, j = 1; i < nums.length; i , j )
dpnums[j] = nums[i];
int[][] coins = new int[dpnums.length][dpnums.length];
for(int i=2; i<dpnums.length; i ) {
for(int j=0; j i<dpnums.length; j ) {
for(int k=j 1; k<j i; k ) {
coins[j][j i] = Math.max(coins[j][j i], coins[j][k] coins[k][j i]
dpnums[j] * dpnums[k] * dpnums[j i]);
}
}
}
return coins[0][dpnums.length-1];
}
}
