find all the palindromes in substring s[1:end-1], and all the palindromes in substring s[end] So the problem is quite clear, when we do recursion, two things should be considered: 1. stop condition: when the search goes to the last position in the string 2. for loop or while loop:...

Except for the first two numbers, each subsequent number in the sequence must be the sum of the preceding two. For example: "112358" is an additive number because the digits can form an additive sequence: 1, 1, 2, 3, 5, 8. 代码语言:javascript 代码运行次数:0 运行 复制 1 + 1 ...
