Expressing numbers in expanded form - JavaScript
Suppose we are given a number 124 and are required to write a function that takes this number as input and returns its expanded form as a string.
The expanded form of 124 is −
'100+20+4'
Example
Following is the code −
const num = 125; const expandedForm = num => { const numStr = String(num); let res = ''; for(let i = 0; i < numStr.length; i++){ const placeValue = +(numStr[i]) * Math.pow(10, (numStr.length - 1 - i)); if(numStr.length - i > 1){ res += `${placeValue}+` }else{ res += placeValue; }; }; return res; }; console.log(expandedForm(num));
Output
Following is the output in the console −
100+20+5
