Given two integer arrays sorted in ascending order and an integer k. Definesum = a + b, whereais an element from the first array andbis an element from the second one. Find thekth smallest sum out of all possible sums. Example
when there is only one sorted array and we want to find the median of that, we need to alter on the length of array is odd or even.because if it is odd, then we just need to exact it’s middle as the median, if not, we need to take average of two element. ...
Find the kth largest element in an unsorted array. Note that it is the kth largest element in the sorted order, not the kth distinct element. Example 1: Input: [3,2,1,5,6,4] and k = 2 Output: 5 1. 2. Example 2: Input: [3,2,3,1,2,4,5,5,6] and k = 4 ...
Partition the Array to Find the Kth Largest/Smallest Element The following is essentially similar to the nth_element algorithm. Each iteration, we pick a pivot element and then we partition the array into two halves, the one that has all elements smaller than it and the others that are large...
