examples the following program is an example of divide-and-conquer programming approach where the binary search is implemented using python binary search implementation in binary searchwe take sorted list of elements and start looking for an element at the middle of the list if the search value matches with the middle value in the listwe complete the search otherwisewe eliminate half of the list of elements by choosing whether to process with the right or left half of the list depending on the value of the item searched this is possible as the list is sorted and it is much quicker than linear search herewe divide the given list and conquer by choosing the proper half of the list we repeat this approach till we find the element or conclude about its absence in the list def bsearch(listval)list_size len(list idx idxn list_size find the middle most value while idx <idxnmidval (idx idxn)/ if list[midval=valreturn midval compare the value the middle most value if val list[midval]idx midval elseidxn midval if idx idxnreturn none initialize the sorted list list [ , , , , , print the search result
