WebIn the first test case, $$$\gcd(5, 15) = 5 > 1$$$, so it's already not lucky, so the length of the lucky chain is $$$0$$$. In the second test case, $$$\gcd(13 + 1, 37 + 1) = \gcd(14, 38) = 2$$$. So, the lucky chain consists of the single pair $$$(13, 37)$$$. WebMar 10, 2024 · Sparse Table is a data structure, that allows answering range queries. It can answer most range queries in O ( log n) , but its true power is answering range minimum queries (or equivalent range maximum queries). For those queries it can compute the answer in O ( 1) time. The only drawback of this data structure is, that it can only be used …
