一道超时的C++编程题求解[ Prime Palindromes]
题目:The number 151 is a prime palindrome because it is both a prime number and a palindrome (it is the same number when read forward as backward). Write a program that finds all prime palindromes in the range of two supplied numbers a and b (5 L >> R && (L || R))
\x09{
\x09\x09if (L % 2 == 0){ L++; }
\x09\x09for (x = L; x
1.if (L % 2 == 0){ L++; } //这句没有必要,只是让程序少循环一次,却增加了计算L%2,而且让程序显得不简洁.另外,我建议是L和R还是用a和b比较好,符合题目要求.
2.for (x = L; x
