JAVA Program Count 1’s in a sorted binary array – Searching and Sorting – A simple solution is to linearly traverse the array. The time complexity of the simple solution is O(n). We can use Binary Search to find count in O(Logn) time.

JAVA 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 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.
Merge Sort for Linked Lists – Searching and Sorting – Merge sort is often preferred for sorting a linked list. The slow random-access performance of a linked list makes some other algorithms (such as quicksort) perform poorly, and others (such as heapsort) completely impossible.
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]
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.
Merge Sort – searching and sorting algorithm – Like QuickSort, Merge Sort is a Divide and Conquer algorithm. It divides input array in two halves.
