A Narcissistic Number is a positive number which is the sum of its own digits, each raised to the power of the number of digits in a given base. In this Kata, we will restrict ourselves to decimal (base 10).
For example, take 153 (3 digits), which is narcisstic:
1^3 + 5^3 + 3^3 = 1 + 125 + 27 = 153
and 1652 (4 digits), which isn't:
1^4 + 6^4 + 5^4 + 2^4 = 1 + 1296 + 625 + 16 = 1938
The Challenge:
Your code must return true or false depending upon whether the given number is a Narcissistic number in base 10.
Error checking for text strings or other invalid inputs is not required, only valid positive non-zero integers will be passed into the function.
function narcissistic(value) {
// Code me to return true or false
let str = String(value)
let result = 0
for(i=1;i<10;i++) {
if (result === value) {
return true
}
result = 0
for(j=0;j<str.length;j++) {
result += (+str[j])**i
}
}
return false
}
