Nptel Week 9 Programming Assignment Answers:

Q.1: Given two strings s1 and s2, write a function subStr that accepts two strings s1 and s2 and will return True if a s2 is a substring of s1 otherwise return False. A substring is a is a contiguous sequence of characters within a string. check input and output following:

Input:

bananamania

nana

Output:

True

Explanation:

S2 which is nana is in bananamania hence it is a substring of s1.

Example 2:

Input:

aabbcc

abc

output:

False

Explanation:

String s1 does not contain string s2 hence the answer is false.

Code:

n=input() m=input() if m in n: print("True",end="") else: print("False",end="")

Q.2: Given two dictionaries d1 and d2, write a function mergeDic that accepts two dictionaries d1 and d2 and return a new dictionary by merging d1 and d2. 

Note: Contents of d1 should be appear before contents of d2 in the new dictionary and in same order. In case of duplicate value retain the value present in d1.

Input:

{1: 1, 2: 2}

{3: 3, 4: 4}

output:

{1: 1, 2: 2, 3: 3, 4: 4}

Code:

def mergeDic(d1,d2): for i in d2: if i not in d1: d1[i]=d2[i] return d1

Q.3: Given an integer n, print all the indexes of numbers in that integer from left to right.

Input:

122345

Output:

1 0 

2 1 2

3 3

4 4

5 5

Explanation:

Given integer 122345. Now printing indexes of numbers from left to right.

The First number is 1 and its index is 0 therefore

1 0 

The second and the third number is 2 and its index is 1,2 therefore

2 1 2

and so on...

Code:

a=str(n) b='' for i in a: if i not in b: b+=i for i in b: print(i,end=" ") for j in range(len(a)): if i==a[j]: print(j,end=" ") print()
