山峰个数【python实现】

思路见此处

def get_mountain_peaks(height):peak_count = 0n = len(height)if n == 0:#如果一个山高都没有，return 0return 0for i in range(1,n-1):if height[i] > height[i-1] and height[i] > height[i+1]:peak_count += 1if height[0] > height[1] and n > 1:#边界情况peak_count += 1if height[-1] > height[-2] and n > 1:peak_count += 1print(peak_count)
def main():height = list(map(int,input().strip("[]").split(",")))get_mountain_peaks(height)if __name__ =="__main__":main()
