why I want to know the time complexity(with explanation). My logic was to store all the K pairs in a map<int , vector> such that the first element of each pair acts as key , its value being a vector of all the
Approach 2: Find Largest and Smallest Vector Elements Another method isfinding largest and smallestby using library functionsstd::max_elementandstd::min_element, respectively. These methods are defined in<algorithm>header. Time complexity of both the methods is linear i.e theta(n). ...
As already discussed, the find() function is used to find the elements in the vector in C++, which finds the very first occurrence of the element in the sequence having a linear time complexity. It takes 3 arguments as input, i.e. first, last, and the element which needs to be search...

std::binary_search() searches in O(logn) time whether std::find() searches in linear time. Example 1 When the searched element is found and have only one instance in the searching range #include <bits/stdc++.h>usingnamespacestd;intmain() { vector<int>arr{1,2,3,8,4,3};intsearching...
in an exponential growth in the number of potential pharmacological combinations that can be tested each year10. As a small number of compounds can yield a large number of combinations7testing all possible pharmacological combinations would be a resource-intensive and time-consuming endeavor. Even ...
Time Complexity: O(k + (n-k)Logk) without sorted output. If sorted output is needed then O(k + (n-k)Logk + kLogk). The C++ implementation of the method is as below: //To heapify a subtree rooted with node i which is//an index in arr[]. n is size of heaptemplate<typename...
When the first specimens of the mosquito were collected in Kerala in the 1970s, they were misidentified as Heizmannia metallica, a species found in Malaysia. Researchers from the ICMR- Vector Control Research Centre (VCRC) in Puducherry collected and reared the mosquito larvae from fallen cocoa ...
