We are required to write a JavaScript function that accepts two string and a number n.
The function matches the two strings i.e., it checks if the two strings contains the same characters.
The function returns true if both the strings contain the same character irrespective of their order or if they contain at most n different characters, else the function should return false.
Example
Following is the code −
const str = 'some random text';
const str2 = 'some r@ndom text';
const deviationMatching = (first, second, num) => {
let count = 0;
for(let i = 0; i < first.length; i++){
if(!second.includes(first[i])){
count++;
};
if(count > num){
return false;
};
};
return true;
};
console.log(deviationMatching(str, str2, 1));Output
This will produce the following output in console −
true
