**sWAP cASE**

### Problem Statement :

You are given a string and your task is to swap cases. In other words, convert all lowercase letters to uppercase letters and vice versa. For Example: Www.HackerRankSolution.in → wWW.hACKERrANKsOLUTION.IN Pythonist 2 → pYTHONIST 2 Input Format: A single line containing a string S. Constraints: 0<len(S)<=1000 Output Format: Print the modified string S.

### Solution :

` ````
Solution in C :
def swap_case(s):
case_change=[]
for i in range(len(s)):
if (s[i].isupper())==True:
case_change.append(s[i].lower())
elif (s[i].islower()==True):
case_change.append(s[i].upper())
else:
case_change.append(s[i])
stri=''
return stri.join(case_change)
if __name__ == '__main__':
s = input()
result = swap_case(s)
print(result)
```

## Palindromic Subsets

Consider a lowercase English alphabetic letter character denoted by c. A shift operation on some c turns it into the next letter in the alphabet. For example, and ,shift(a) = b , shift(e) = f, shift(z) = a . Given a zero-indexed string, s, of n lowercase letters, perform q queries on s where each query takes one of the following two forms: 1 i j t: All letters in the inclusive range from i t

Taylor loves trees, and this new challenge has him stumped! Consider a tree, t, consisting of n nodes. Each node is numbered from 1 to n, and each node i has an integer, ci, attached to it. A query on tree t takes the form w x y z. To process a query, you must print the count of ordered pairs of integers ( i , j ) such that the following four conditions are all satisfied: the path from n

One of the most important skills a programmer needs to learn early on is the ability to pose a problem in an abstract way. This skill is important not just for researchers but also in applied fields like software engineering and web development. You are able to solve most of a problem, except for one last subproblem, which you have posed in an abstract way as follows: Given an array consisting
