int gcd(a, b)int a;int b;{if (b == 0)return a;return gcd(b, (a % b));} 使用GCC 编译时,它会完美地编译通过(如预期的那样),然而使用 G++ 编译时,会出现另一组错误。 gcd.c:3:9: error: 'a' was not declared in this scope3 | int gcd(a, b)| ^gcd.c:3:12: error: 'b'...
CodeForce-803C Maximal GCD(贪心数学) Maximal GCD CodeForces - 803C 现在给定一个正整数n。你需要找到k个严格递增的正整数a1, a2, ..., ak,满足他们的和等于n并且他们的最大公因数尽量大。 如果不可能请输出-1。 这k个数的gcd的必定是n的因数,于是变成枚举n的因数,可以知道只需要枚举 1~sqrt(...
TSAN has pointed out an issue in my code that stems from assuming that the value returned by NSStringFromSelector is immutable, and that the function itself is re-entrant. I’d like to check both those assumptions against the actual sources... assuming they haven't changed in macOS Sequoia ...

枚举gcdgcd,然后计算剩下的那个数能不能分成kk个递增的数。 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50
