Elements in map: [ 1, 2] [ 4, 5] [ 8, 5] C++ Copyset和map的变体Set和Map,都存储惟一值和排序值。但是如果我们没有这样的要求,我们使用multiset/multimap和unordered_set/unordered_map。MultimapMultimap不允许通过索引存储元素。// CPP program to demonstrate working of Multimap #include <bits/std...
Given two integersLandR, find the count of numbers in the range[L, R](inclusive) having a prime number of set bits in their binary representation. (Recall that the number of set bits an integer has is the number of1s present when written in binary. For example,21written in binary is101...
