Have a nice holiday and thank you for your help
I have already tried to solve my problem but I have not given enough information I will try to reformulate it
I want the output to be these numbers
input 14:1 output 141
input 13:8 output 141
input 13:18 output 241
input 18:13 output 291
the calculation is as follows input 14:1 4+1 is not greater than 9 so the number one is the rest and we leave it at the end and add 14 before it output 141
input 13:8 3 + 8 is greater than 9 (11) so I add 1 to 3 of them become 4 and 1 is the rest we add at the end output 141
input 13:18 output 241
input 18:13 output 291
trying to help me here is an example code they thank a woman from Germany for it
const
fn = string => {
const
sum = (a, b) => (a + b).toString().padStart(2, 0).split(''),
[a, b] = string.split(':').map(s => s.padStart(2, 0)),
result = [];
let i = 2;
while (i--) {
const sum = +a[i] + +b[i];
result[i] = sum > 10
? +[+a[i] + Math.floor(sum / 10), sum % 10].join('')
: sum === 10 ? 1 : sum;
}
return result.join('');
};
console.log(fn('13:18')); // I want 241 correct output 241
console.log(fn('18:13')); // I want 291 correct output 291
console.log(fn('13:15')); // I want 28 correct output 28
console.log(fn('15:13')); // I want 28 correct output 28
console.log(fn('14:1')); // I want 141 bad output 15
console.log(fn('13:8')); // I want 141 correct output 141
console.log(fn('78:96')) // I want 174 bad output "8694"
this code calculates some results correctly and some incorrectly
if less than 10 console.log (fn ('14: 1 ')); // I want this 141 output / gives a bad output "15"
As per the logic you've explained, and assuming the numbers will be max of 2 length.
P.S. +(plus sign) prefix converts string to integer runtime
First Solution =>
const fn = (string) => {
const [a,b] = string.split(':').map(s=>s.padStart(2,0)), result=[];
// for first position
result[0] = +a[0] + +b[0];
// for second position
let secondIndexTotal = (+a[1] + +b[1]).toString();
result[1] = +secondIndexTotal > 9 ? (+a[1] +
+secondIndexTotal[0]).toString() + secondIndexTotal[1] : a[1]+b[1];
return result.join('');
}
console.log(fn('13:18')); // output 241
console.log(fn('18:13')); // output 291
console.log(fn('13:15')); // output 235
console.log(fn('15:13')); // output 253
console.log(fn('14:1')); // output 141
console.log(fn('13:8')); // output 141Updated Solution =>
const fn = (string) => {
const [a, b] = string.split(":").map((s) => s.padStart(2, 0)),
result = [];
// for second position
const secondIndexTotal = (+a[1] + +b[1]).toString();
result[1] = +secondIndexTotal > 9 ? secondIndexTotal[1] : b[1];
// for first position
const firstIndexTotal = +a[0] + +b[0];
result[0] =
firstIndexTotal > 9
? firstIndexTotal + (+secondIndexTotal > 9 ? +secondIndexTotal[0] : 0)
: firstIndexTotal.toString() +
(+a[1] + (+secondIndexTotal > 9 ? +secondIndexTotal[0] : 0));
return result.join("");
};
console.log(fn("13:18")); // output 241
console.log(fn("18:13")); // output 291
console.log(fn("78:96")); // output 174
console.log(fn("14:1")); // output 141
console.log(fn("13:15")); // output 235
console.log(fn("15:13")); // output 253
