Chinese Description:Given a number triangle, find the smallest path from the top to the bottom and the. Each step can be moved to an adjacent number on the following line. ExamplesFor example, give the following number triangles:[[2],[3,4],[6,5,7],[4,1,8,3]]Minimum path from top to bottom and 11 (2 + 3 + 5 + 1 = 11). AttentionIf you do this with only the extra space complexity O (n), you can get a bonus, where n is the total number of rows in the numb

After listening to the old elders, he was so angry that the primary and secondary education in Guangzhou has lost its ancestor's clothes. He said that the language behavior of our descendants was assimilated by foreign families, and the current usage of Cantonese in primary school students is far inferior to that in the early days of liberation. At that time, there were no slogans to promote Mandarin. Students could learn a lot of authentic Cantonese culture in class. He talked about a Cantonese
