I was solving a problem in leet code, Solution I came up with made all test cases passed except for one. Input of that test case is an array = [6,1,4,5,3,9,0,1,9,5,1,8,6,7,0,5,5,4,3]. so I have convert the array into a number add 1 to entire number and then convert it back to array format with result, in my solution one step before final statement, I have used parseInt("6145390195186705543")+1 then I convert to string and split and then convert to number. but during parseInt(), this in-built method is not able to convert after 15th digits, im getting output as [6145390195186705000], sending 0's after 15 digits, so does anyone has any idea on how to convert a string of number length more than 16 to Number P.S: I have tried bigInt() method, techincally it would work but for the problem bigInt() is not working and output isnt working
var plusOne = function(digits) {
let y = digits.map(String);
let z = ''
for (let i = 0; i < y.length; i++) {
z += y[i];
}
let a = (parseInt(z) + 1).toString().split('')
return a.map(Number)
};
Loop backwards over the digits, and
function addOne(digitArray) {
for (let i = digitArray.length - 1; i >= 0; i--) {
if (digitArray[i] < 9) {
digitArray[i] += 1
break
} else {
digitArray[i] = 0
if (i === 0) {
digitArray.unshift(1)
}
}
}
return digitArray
}
console.log(addOne([])) // []
console.log(addOne([ 0 ])) // [ 1 ]
console.log(addOne([ 9 ])) // [ 1, 0 ]
console.log(addOne([ 1, 0 ])) // [ 1, 1 ]
console.log(addOne([ 1, 9 ])) // [ 2, 0 ]
console.log(addOne([ 9, 9 ])) // [ 1, 0, 0 ]
console.log(addOne([ 6, 1, 4, 5, 3, 9, 0, 1, 9, 5, 1, 8, 6, 7, 0, 5, 5, 4, 3 ]))
// [ 6, 1, 4, 5, 3, 9, 0, 1, 9, 5, 1, 8, 6, 7, 0, 5, 5, 4, 3 ]
