Can you solve this real interview question? Count Good Numbers - A digit string is good if the digits (0-indexed) at even indices are even and the digits at odd indices are prime (2, 3, 5, or 7). * For example, "2582" is good because the digits (2 and

If the current number of teams is even, each team gets paired with another team. A total of n / 2 matches are played, and n / 2 teams advance to the next round. If the current number of teams is odd, one team randomly advances in the tournament, and the rest gets paired. A tota...
由于奇数和奇数间存在偶数,所以一定存在其他子数组 [l,r] 满足[l,r] 包含[odd[i],odd[i+k−1]] 且[l,r] 里的奇数个数为 k 个,那么这个需要怎么统计呢?由于我们已经记录了每个奇数的下标,所以我们知道对于第 i 个奇数,它的前一个奇数的下标为 odd[i−1],也就是说 (odd[i−1],odd[i]) ...
