Missing letter from strings in JavaScript
We have a string of length m that contains first m letters of the English alphabets, but somehow, one element went missing from the string. So now the string contains m-1 letters.
We are required to write a function that takes in one such string and returns the missing element from the string
Therefore, let’s write the code for this function −
Example
The code for this will be −
const str = "acdghfbekj";
const missingCharacter = str => {
// to make the function more consistent
const s = str.toLowerCase();
for(let i = 97; ; i++){
if(s.includes(String.fromCharCode(i))){
continue;
};
return String.fromCharCode(i);
};
return false;
};
console.log(missingCharacter(str));Output
The output in the console will be −
i
