Python subjective question for competitive exam (36)

Q1.what is the output of code.

r=[2,1,0,3]
for i in r:
        r[s]=0
print(r)

output
first r[2]=0
so list [2,1,0,3]
next r[1]=0
so list[2,0,0,3]
nextr[0]=0
so list [0,0,0,3]
next r[3]=0
so list[0,0,0,0]

[0,0,0,0]

Q2.Program to find common b/w three sorted list.

def fc(a,b,c):
    n=len(a)
    m=len(b)
    k=len(c)
    for i in range(0,n):
        for j in range(0,m):
            if(a[i]==b[j]):
                for k in range(0,k):
                    if(a[i]==c[k]):
                        print(a[i])
                        
a=[1,2,3]
b=[2,3,4]
c=[2,3,5]
fc(a,b,c)

        for j in range(i,n+1):

            for k in range(i,j):
                print(a[k], end="")
            print()
                
                
a=[1,2,3,4]
suba(a)
