python - How to merge two sequences in single sequence in an alternate manner without using arrays?

Question

for eg if sequence 1 : <1,3,5> and sequence 2 : <2,6,8,11,12>
than the result should be <1,2,3,6,5,8,11,12>

I tried to solve it using loops but what I am getting is a repeated structure

Answer 1

i=0
j=0
N=len(L1)
M=len(L2)
L=[]
turn=True
while(i<N and j<M):
    if turn:
        L.append(L1[i])
        i+=1
    else:
        L.append(L2[j])
        j+=1
    turn=!turn
while(i<N):
    L.append(L1[i])
    i+=1
while(j<M):
    L.append(L2[j])
    j+=1
print(L)

THis can do the trick for you What Is being done is That I am keeping a boolean Turn to Alternate turns to select from the two arrays If You have any doubt regarding the loop logic I can elaborate a little. simple turn= !turn => ALternates turns on each iteration
