C++ programming – Given a sorted array and a number x, find the pair in array whose sum is closest to x – Searching and sorting – Given a sorted array and a number x, find a pair in array whose sum is closest to x.
C programming – Given a sorted array and a number x, find the pair in array whose sum is closest to x – Searching and sorting.- Given a sorted array. find a pair in array whose sum is closest to x.
Search in an almost sorted array – Searching and Sorting – A simple solution is linearly search given key in given array.Time complexity of solution is O(n).We cab modify binary search to do it in O(Logn) time.
Sort a nearly sorted (K sorted) array – Searching and sorting – Given an array of n elements, where each element is at most k away from its target position.
Find the Minimum length Unsorted Subarray, sorting which makes the complete array sorted -Searching and sorting – Given an unsorted array arr[] of size n. find the minimum length subarray arr[s..e]
Lower bound for comparison based sorting algorithms – Searching and sorting – A sorting algorithm is comparison based if it uses comparison operators to find the order between two numbers.
Which sorting algorithm makes minimum number of memory writes – Searching and Sorting – Minimizing the number of writes is useful when making writes to some huge data set is very expensive, such as with EEPROMs or Flash memory, where each write reduces the lifespan of the memory.
stability in sorting algorithms – Searching and Sorting – Some sorting algorithms are stable by nature like Insertion sort, Merge Sort, Bubble Sort, etc. And some sorting algorithms are not, like Heap Sort, Quick Sort.
Cycle Sort – Searching and sorting – Cycle sort is an in-place sorting Algorithm,unstable sorting algorithm, a comparison sort that is theoretically optimal in terms of the total number of writes to the original array
