[746] Min Cost Climbing Stairs

竟然被macro 整到，覺得不開心XD 記得前前後後括號都要給它括好括滿！！！

#define MIN(A,B) ((A<B)?(A):(B))

int minCostClimbingStairs(int* cost, int costSize){

int *minCost=calloc(costSize, sizeof(int));

minCost[0]=cost[0];

minCost[1]=cost[1];

for (int i=2;i<costSize;i++)

minCost[i]= (MIN(minCost[i-1],minCost[i-2])+cost[i]);

return MIN(minCost[costSize-2],minCost[costSize-1]);

}
