Find char combination in array of strings JavaScript
We have to write a function that accepts an array of strings and a string. Our job is to check whether the array contains any sequence or subsequence of the string as its element or not, and the function should return a boolean based on this fact.
For instance −
const x = 'ACBC'; const arr = ['cat','AB']; const arr2 = ['cat','234','C']; const arr3 = ['cat','CC']; const arr4 = ['cat','BB']; console.log(containsString(arr,x)) // true console.log(containsString(arr2,x)) // true console.log(containsString(arr3,x)) // true console.log(containsString(arr4,x)) // false
Therefore, let’s write the code for this function −
Example
const x = 'ACBC';
const arr = ['cat','AB'];
const arr2 = ['cat','234','C'];
const arr3 = ['cat','CC'];
const arr4 = ['cat','BB'];
const splitSort = function(){
return this.split("").sort().join("");
};
String.prototype.splitSort = splitSort;
const containsString = (arr, str) => {
const sorted = str.splitSort();
for(let i = 0; i < arr.length; i++){
const sortedEl = arr[i].splitSort();
if(sorted.includes(sortedEl)){
return true;
}
};
return false;
}
console.log(containsString(arr,x)) // true
console.log(containsString(arr2,x)) // true
console.log(containsString(arr3,x)) // true
console.log(containsString(arr4,x)) // falseOutput
The output in the console will be −
true true true false
