Given a string of lower and uppercase characters, the task is to find that how many characters are at same position as in English alphabet.
Examples:
Input: ABcED Output : 3 First three characters are at same position as in English alphabets. Input: geeksforgeeks Output : 1 Only 'f' is at same position as in English alphabet Input : alphabetical Output : 3
For this we can have simple approach:
1) Initialize result as 0. 2) Traverse input string and do following for every character str[i] a) If 'i' is same as str[i] - 'a' or same as str[i] - 'A', then do result++ 3) Return result
C++
// C++ program to find number of characters at same // position as in English alphabets #include<bits/stdc++.h> using namespace std; int findCount(string str) { int result = 0; // Traverse input string for ( int i = 0 ; i < str.size(); i++) // Check that index of characters of string is // same as of English alphabets by using ASCII // values and the fact that all lower case // alphabetic characters come together in same // order in ASCII table. And same is true for // upper case. if (i == (str[i] - 'a' ) || i == (str[i] - 'A' )) result++; return result; } // Driver code int main() { string str = "AbgdeF" ; cout << findCount(str); return 0; } |
Java
// Java program to find number of // characters at same position // as in English alphabets class GFG { static int findCount(String str) { int result = 0 ; // Traverse input string for ( int i = 0 ; i < str.length(); i++) // Check that index of characters // of string is same as of English // alphabets by using ASCII values // and the fact that all lower case // alphabetic characters come together // in same order in ASCII table. And // same is true for upper case. { if (i == (str.charAt(i) - 'a' ) || i == (str.charAt(i) - 'A' )) { result++; } } return result; } // Driver code public static void main(String[] args) { String str = "AbgdeF" ; System.out.print(findCount(str)); } } // This code is contributed by Rajput-JI |
Python3
# Python program to find number of # characters at same position as # in English alphabets # Function to count the number of # characters at same position as # in English alphabets def findCount( str ): result = 0 # Traverse the input string for i in range ( len ( str )): # Check that index of characters of string is # same as of English alphabets by using ASCII # values and the fact that all lower case # alphabetic characters come together in same # order in ASCII table. And same is true for # upper case. if ((i = = ord ( str [i]) - ord ( 'a' )) or (i = = ord ( str [i]) - ord ( 'A' ))): result + = 1 return result # Driver Code str = 'AbgdeF' print (findCount( str )) # This code is contributed # by SamyuktaSHegde |
