Help me in solving CHFRICH problem

My issue

I’m getting the right answers, could you guys help me to see what is wrong?

My code

``````// your code goes here
process.stdin.resume()
process.stdin.setEncoding('utf-8')
let data=''
process.stdin.on('data',(input)=>{
data = input.split('\n')
})

process.stdin.on('end',()=>{
let i=0
const numberTest = data.shift()
let finalData = data.map((d)=> d.split(' '))
while(i<numberTest){
console.log(yearsToBecome(...finalData[i]) )
i++
}
})

function yearsToBecome(A,B,X){
return (B - A)/X
}

``````

@leonar6
plzz refer the following solution for debugging your code.

``````process.stdin.resume();
process.stdin.setEncoding('utf8');

let inputStdin = "";

process.stdin.on('data', function (data) {
inputStdin += data;
});

process.stdin.on('end', function () {
start();
});

function start() {
let inputArr = inputStdin.split('\n')
let T = inputArr[0]
inputArr.shift()
let N = inputArr

for (let i = 0; i < T; i++) {
let elementArray = N[i].split(' ')
console.log((elementArray[1]-elementArray[0])/elementArray[2])
}
}
