Just now watched session 6 recorded video.
Thanks Syed, Nice session and detailed explanation.
I have came across another resource about Big O notation in recent days. Thought it may be helpful to learners in this workshop

Hi Syed and all,

I tried to implement the binary search algorithm syed explained last session.

github.com

parameshwar-A/dsa-notes/blob/main/binary_search.py



def binary_search(element, data, start, end, mid):
    if element>data[mid]:
        start=mid+1
        mid=(start+end)//2
        binary_search(element, data, start, end, mid)

    elif element<data[mid]:
        print("less")
        end=mid-1
        mid=(start+end)//2
        binary_search(element, data, start, end, mid)

    elif data[mid]==element:
        print(data.index(element))


test_data=[1, 2, 3, 4, 5, 6, 7, 8, 9]
#Remember the input needs to be sorted before processed

Check it out and let me know if any fix needs to be done

syedjafer · March 22, 2023, 2:25pm

data.index(element)

will give the index by searching again. You can print ‘mid’ value.

Yes, I should have given that. Focusing on algorithm too much missed the simple way

parameshwar · March 23, 2023, 3:36am

Hi Syed and all,

I have implemented the merge sort we discussed in last class.
As I asked, I have implemented this in for loop version

github.com

parameshwar-A/dsa-notes/blob/main/merge_sort.py

def merge_sort(data):
    if len(data)>1:
        mid=len(data)//2
        left=data[:mid]
        right=data[mid:]
        merge_sort(left)

        merge_sort(right)

        i=j=0
        for k in range(len(data)):
            if i<len(left) and j<len(right):
                if left[i]<right[j]:
                    data[k]=left[i]
                    i+=1
                else:
                    data[k]=right[j]
                    j+=1
            elif i<len(left):
                data[k]=left[i]
