I have an array of numbers. I need to find the maximum number of consecutive 1s in the array.
var arr = [1, 1, 3, 2, 3, 1, 1, 1];
const maxOne = (arr) => {
for (var i = 0; i < arr.length; i++) {
let count = 0;
let result = 0;
if (arr[i] ==1) {
count += 1;
result = Math.max(result, count);
} else {
count = 0
}
return result
}
}
console.log(maxOne(arr));
desired output: 3
my output : 1
I am not sure where I am going wrong
You algorithm works, you just did few misstakes:
const maxOne = (arr) => {
let count = 0;
let result = 0;
for (var i = 0; i < arr.length; i++) {
if (arr[i] === 1) {
count += 1;
result = Math.max(result, count);
} else {
count = 0
}
}
return result
}
You can do like this.
let arr=[1,2,3,1,1,2,1,1,12,1,1,1,1];
let count=0;
for(let i=0;i<arr.length;i++){
arr[i]==1 ? count+=1 :count=0;
}
console.log(count).
