Algorithms Column Sort Algorithm Column Sort Algorithm is a non-traditional sorting algorithm for Distributed Memory Clusters (DMC) (means multiple processors). It is a generalization of odd-even merge sort and is used in a parralel system where multiple CPUs are available for use.
Algorithms Shift OR algorithm for String Matching Shift OR algorithm uses bitwise techniques to check whether the given pattern is present in the string or not. It is efficient if the pattern length is lesser than the memory-word size of the machine
