Hacckerank - sWaP problem

 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.HackerRank.com → wWW.hACKERrANK.COM
Pythonist 2 → pYTHONIST 2

Function Description

Complete the swap_case function in the editor below.

swap_case has the following parameters:

  • string s: the string to modify

Returns

  • string: the modified string

Input Format

A single line containing a string .

Constraints

Sample Input 0

HackerRank.com presents "Pythonist 2".

Sample Output 0

hACKERrANK.COM PRESENTS "pYTHONIST 2".
def swap_case(s):
    #print(len(s))
    
    res=""
    for i in range(len(s)):
        
        
        if (ord(s[i])>=ord('a') and ord(s[i])<=ord('z')):
            a=ord(s[i])-32
            res=res+chr(a)
            
        elif (ord(s[i])>=ord('A') and ord(s[i])<=ord('Z')):
            b=ord(s[i])+32
            res=res+chr(b)
        else:
            c=ord(s[i])
            res=res+chr(c)
            
    return res

if __name__ == '__main__':
    s = input()
    result = swap_case(s)
    print(result)

Find the Runner-Up Score!

  Given the participants' score sheet for your University Sports Day, you are required to find the runner-up score. You are given     scores. Store them in a list and find the score of the runner-up. Input Format The first line contains  . The second line contains an array     of   integers each separated by a space. Constraints Output Format Print the runner-up score. Sample Input 0 5 2 3 6 6 5 Sample Output 0 5 Explanation 0 Given list is  . The maximum score is  , second maximum is  .

Print All Substrings

  For a given input string(str), write a function to print all the possible substrings. Substring A substring is a contiguous sequence of characters within a string. Example: "cod" is a substring of "coding". Whereas, "cdng" is not as the characters taken are not contiguous Input Format: The first and only line of input contains a string without any leading and trailing spaces. All the characters in the string would be in lower case. Output Format: Print the total number of substrings possible, where every substring is printed on a single line and hence the total number of output lines will be equal to the total number of substrings. Note: The order in which the substrings are printed, does not matter. Constraints: 0 <= N <= 10^6 Where N is the length of the input string. Time Limit: 1 second Sample Input 1: abc Sample Output 1: a ab abc b bc c  Sample Input 2: co Sample Output 2: c co o #include <iostream> #include <cstring> us...
