Given a string of English alphabets. The task is, for every character in the string print its position in the English alphabets.
Note: The characters in the string are considered to be case-insensitive. That is, both ‘A’ and ‘a’ are at first position.
Output: 7 5 5 11 19
‘G’ is the 7th character of the alphabets
‘e’ is the 5th and so on…
Output: 1 12 7 15 18 9 20 8 13 19
A letter’s position in Alphabet can easily be found by performing logical AND operation with the number 31.
Note that this is only applicable on letters and not special characters.
Every letter has an ASCII value which can be represented in binary form. Performing the bitwise and of this value with the number 31 will give the letter’s position in the alphabets.
Below is the implementation of the above approach:
7 5 5 11 19
- Count characters at same position as in English alphabet
- Find the most valued alphabet in the String
- Find the Mid-Alphabet for each index of the given Pair of Strings
- Find average of two numbers using bit operation
- Find position of the only set bit
- Find the value at kth position in the generated array
- Find position of the given number among the numbers made of 4 and 7
- Find position of left most dis-similar bit for two numbers
- InfyTQ 2019 : Find the position from where the parenthesis is not balanced
- Find the number of occurrences of a character upto preceding position
- Latin alphabet cipher
- Smallest alphabet greater than a given character
- Transform One String to Another using Minimum Number of Given Operation
- Sub-string that contains all lowercase alphabets after performing the given operation
- Next higher number using atmost one swap operation
