If the array consists of only positive numbers the problem can be efficiently solved using only the sliding window technique as discussed here. Input: source = 0, destination = 4. Now we retrieve min values (2 at a time) of array, by. Calendar representation of data. We initialize distances to all vertices as minus infinite and distance to source as 0, then we find a topological sorting of the graph. Find the first repeating element in an array of integers. The idea is simple, we find all divisors of a number one by one. Contests. Find the length of the longest sub-sequence such that elements in the subsequence are consecutive integers, the consecutive numbers can be in any order.
