There’s a problem with the test cases. I got AC with this code,

    String ab = inp.next();
    char c [] = ab.toCharArray();
    int temp=0,storage;
    storage =0;
    for(int i=0;i<c.length ;i++)
    {
        int count =0;
        for(int j=0;j<c.length ;j++)
        {
            if(c[i]==c[j])
            {
                count++ ;
            }
        }
        if(count>storage)
        {
            storage =count;
            temp =c[i]-'0';
        }

    }
    System.out.println(temp);

It’s a number not a string.If i input 1213 in your code then 1213 will only store in index 0.

what is the test case 4?My code isn’t getting past test case 4.But i have checked my code for every posssible value it’s properly working.What’s the problem here please someone tell me.

my code is not working for testcase 3 what is the problem?

#include<bits/stdc++.h>

using namespace std;

int main() {
	string s;
	cin >> s;
	int a[10];
    a[0] = count(s.begin(),s.end(),'0');
    a[1] = count(s.begin(),s.end(),'1');
	a[2] = count(s.begin(),s.end(),'2');
	a[3] = count(s.begin(),s.end(),'3');
	a[4] = count(s.begin(),s.end(),'4');
	a[5] = count(s.begin(),s.end(),'5');
	a[6] = count(s.begin(),s.end(),'6');
	a[7] = count(s.begin(),s.end(),'7');
	a[8] = count(s.begin(),s.end(),'8');
	a[9] = count(s.begin(),s.end(),'9');
	int max = *max_element(a,a+9);
	cout << a[max] << endl;
	return 0;
}

Plz check the last statement . Will your code work properly ?

#include
#include

using namespace std;

int main() {
int N = 0, count[10], num;

cin>>N;

for(int i = 0; i < 10; i++ ){
    count[i] = 0;
}

while(N != 0){
    num = N%10;
    count[num]++;
    N = N/10;
}

int max = count[0], max_digit = 0, max_digit_1 = 0;
for(int i = 0; i <= 9; i++){
    if(max == count[i] && max != 0){
        max_digit_1 = i;
    }
    if(max < count[i]){
        max = count[i];
        max_digit = i;
    }
}

if(max_digit_1 != 0){
    (max_digit < max_digit_1) ? cout<<max_digit<<endl : cout<<max_digit_1<<endl;
}else {
    cout<<max_digit<<endl;
}

return 0;

}

3rd case got wrong answer.

In my MinGW compiler I got right answers.But in this website’s compiler giving me wrong answers.But why?

#include<stdio.h>

int main()

{

char num[10];

int i,a,count[10]={0},len,max=0;

scanf("%s",num);

for(i;num[i];i++){}

len = i-1;

for(i;i>=0;i--){

    a = num[i] - '0';

    switch(a){

        case 0:

            count[0]++;

            break;

        case 1:

            count[1]++;

            break;

        case 2:

            count[2]++;

            break;

        case 3:

            count[3]++;

            break;

        case 4:

            count[4]++;

            break;

        case 5:

            count[5]++;

            break;

        case 6:

            count[6]++;

            break;

        case 7:

            count[7]++;

            break;

        case 8:

            count[8]++;

            break;

        case 9:

            count[9]++;

            break;

        default:

            break;

    }

}

for(len;len >= 0;len--){

    if(max <= count[len]){

        max = count[len];

        i = len;

    }

}

printf("%d",i);

return 0;

}

It should work. But why is it giving the wrong answer while getting input from test case 4?

#include <stdio.h>

int main()
{
    int num, count, result, digit[10];
    scanf("%d", &num);

    for (int i = 0; i < 10; i++) {
        digit[i] = 0;
    }
    while (num != 0) {
        digit[num % 10]++;
        num /= 10;
    }
    count = 0;
    for (int i = 0; i < 10; i++) {
        if (digit[i] > count) {
            count = digit[i];
            result = i;
        }
    }

    printf("%d\n", result);

    return 0;
}```

@integer The statement has been updated. Please check the problem statement again… especially the input specification. Previously the contraint was formatted incorrectly.

Sorry for the inconvenience.
