Password Decryption - Problem Solving (Basic) certification | HackerRank
Password decryption.
- Initially i = 0.
- If s[i] is lowercase and the next character s[i+1] is uppercase, swap them, add a '*' after them, and move to i+2.
- If s[i] is a number, replace it with o, place the original number at the start, and move to i+1.
- Else, move to i+1.
- Stop if iis more than or equal to the string length. Otherwise, go to step 2.
- The original string always contains digits from 1 to 9 and does not contain 0.
- The original string always contains only alpha-numeric characters.
Function Description
Constraints.
- 1 ≤ length of s ≤ 105
- scan contain Latin alphabet characters (a-z, A-Z), numbers (0-9), and the character '*'.
Solution in Python:
| import math import os import random import re import sys # # Complete the 'decryptPassword' function below. # # The function is expected to return a STRING. # The function accepts STRING s as parameter. # def decryptPassword(s): s = list(s) i = 0 while i < len(s) and s[i].isdigit() and s[i] != "0": i += 1 for j, k in enumerate([l for l in range(i, len(s)) if s[l] == "0"]): s[k] = s[i - j - 1] for j in range(i, len(s)): if s[j] == "*": s[j - 1], s[j - 2] = s[j - 2], s[j - 1] return "".join(s[i:]).replace("*", "") if __name__ == '__main__': fptr = open(os.environ['OUTPUT_PATH'], 'w') s = input() result = decryptPassword(s) fptr.write(result + '\n') |

Breaking the Records
Maria plays college basketball and wants to go pro. Each season she maintains a record of her play. She tabulates the number of times she breaks her season record for most points and least points in a game. Points scored in the first game establish her record for the season, and she begins counting from there.
Scores are in the same order as the games played. She tabulates her results as follows:
Given the scores for a season, determine the number of times Maria breaks her records for most and least points scored during the season.
Function Description
Complete the breakingRecords function in the editor below.
breakingRecords has the following parameter(s):
- int scores[n]: points scored per game
- int[2]: An array with the numbers of times she broke her records. Index is for breaking most points records, and index is for breaking least points records.
Input Format
The first line contains an integer , the number of games. The second line contains space-separated integers describing the respective values of .
Constraints
Sample Input 0
Sample Output 0
Explanation 0
The diagram below depicts the number of times Maria broke her best and worst records throughout the season:
She broke her best record twice (after games and ) and her worst record four times (after games , , , and ), so we print 2 4 as our answer. Note that she did not break her record for best score during game , as her score during that game was not strictly greater than her best record at the time.
Sample Input 1
Sample Output 1
Explanation 1
She broke her best record four times (after games , , , and ) and her worst record zero times (no score during the season was lower than the one she earned during her first game), so we print 4 0 as our answer.

Nearly Similar Rectangles. Recently, while researching about similar rectangles, you found the term "Nearly Similar Rectangle." Two rectangles with sides (a, b) and (c,d) are nearly similar only if a/c = b/d. The order of sides matter in this definition, so rectangles [4, 2] and [6,3] are nearly similar, but rectangles [2, 4] and [6,3] are not ...
Problem Solving. Solving problems is the core of computer science. Programmers must first understand how a human solves a problem, then understand how to translate this "algorithm" into something a computer can do, and finally, how to write the specific code to implement the solution. At its core, problem-solving focuses on the study ...

If s [i] is a number, replace it with o, place the original number at the start, and move to i+1. Else, move to i+1. Stop if iis more than or equal to the string length. Otherwise, go to step 2. There's even an example mentioned in the notebook. When encrypted, the string "hack3rr4nk" becomes "43Ah*ckorronk".
