Check if lowercase and uppercase characters are in same order
Given a string str containing only lower and uppercase alphabets. The task is to check if both lowercase characters and uppercase characters follow the same order respectively.
Note: If a character occurs more than once in lowercase then the occurrence of the same character in the uppercase should be same.
Examples:
Input: str = "geeGkEEsKS" Output: Yes Lowercase = geeks, Uppercase = GEEKS Input: str = "GeEkKg" Output: No Lowercase = ekg, Uppercase = GEK
Approach:
- Traverse the string.
- Store the lowercase alphabets and uppercase alphabets in two separate strings lowerStr and upperStr respectively.
- Convert lowercase string to uppercase.
- Check if both uppercase strings are equal or not.
- Print Yes if equal, else print No.
Below is the implementation of above approach:
C++
// C++ program to check if lowercase and // uppercase characters are in same order #include <bits/stdc++.h> using namespace std; // Function to check if both the // case follow the same order bool isCheck(string str) { int len = str.length(); string lowerStr = "", upperStr = ""; // Traverse the string for (int i = 0; i < len; i++) { // Store both lowercase and uppercase // in two different strings if (str[i] >= 65 && str[i] <= 91) upperStr = upperStr + str[i]; else lowerStr = lowerStr + str[i]; } // using transform() function and ::toupper in STL transform(lowerStr.begin(), lowerStr.end(), lowerStr.begin(), ::toupper); return lowerStr == upperStr; } // Driver code int main() { string str = "geeGkEEsKS"; isCheck(str) ? cout << "Yes" : cout << "No"; return 0; } |
