**Programming Assignment**

**Question 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.Input:bananamaniananaOutput:True**

**Solution:**

```
def subStr(s1, s2):
M = len(s1)
N = len(s2)
for i in range(M - N + 1):
flag = True
for j in range(N):
if (s1[i + j] != s2[j]):
flag = False
break
if flag :
return True
return False
if __name__ == "__main__":
s1 = input()
s2 = input()
print(subStr(s1, s2),end="")
```

**Question 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}**

**Solution:**

```
def mergeDic(d1, d2):
dic = {}
for key,value in d1.items():
dic[key] = value
for key,value in d2.items():
if key not in dic.keys():
dic[key] = value
return dic
key = list(map(int, input().split()))
val = list(map(int, input().split()))
d1 = {}
for i in range(len(key)):
d1[key[i]] = val[i]
d2 = {}
key = list(map(int, input().split()))
val = list(map(int, input().split()))
for i in range(len(key)):
d2[key[i]] = val[i]
print(mergeDic(d1, d2))
```

**Solution:**

```
n = str(n)
dic = {}
for i in range(len(n)):
if n[i] not in dic.keys():
dic[n[i]] = [i]
else:
dic[n[i]].append(i)
for key, value in dic.items():
print(key, end= ' ')
for i in value:
print(i, end= ' ')
print()
```
