1. Playing with Number
static int[] shiftArray(int input1, int[] input2, int input3)
{
int ar[]=new int[input2.length];
int j=0;
for(int i=input3;i<input2.length;i++)
{
ar[j++]=input2[i];
}
for(int i=0; i<input3;i++)
{
ar[j++]=input2[i];
}
return ar;
}
Test cases
input1=7;
input2[]= {1,2,3,4,5,6,7};
input3=2;
output:
3 4 5 6 7 1 2
Array Sort(nick checks)
private static int getCount(int input1, int[] input2)
{
int ar[]=new int[input2.length];
for(int i =0;i<input2.length;i++)
{
ar[i]=input2[i];
}
Arrays.sort(ar);
int num=ar[0];
for(int i=0;i<input2.length;i++)
{
if(ar[i]!=num)
return 0;
num++;
}
return 1;
}
Test Case:
input1:6
input2[]: {3,7,2,5,4,6}
output:
1
2. Fancy Occurrence
private static String fancyOcc(String input1, String input2)
{
String s="";
char com=input2.charAt(0);
for(int i= 0; i<input1.length();i++)
{
char ch=input1.charAt(i);
if(ch!=com)
s=s+ch;
}
return s;
}
Test Case:
input1:Welcome to metti
input2:i
output:
Welcome to mett
3. String Within String
private static String isPermutation(String input1,String input2)
{
input1=input1.toLowerCase();
input2=input2.toLowerCase();
int arr1[] = new int[26];
int arr2[] = new int[26];
for(int i=0; i<input1.length();i++)
{
char ch = input1.charAt(i);
arr1[ch-97]++;
}
for(int i=0;i<input2.length();i++)
{
char ch1 = input2.charAt(i);
arr2[ch1-97]++;
if(arr1[ch1-97]<arr2[ch1-97])
return "no";
}
return "yes";
}
Test Case:
input1: abab
input2: ab
output:
yes
4. Palindrome
private static int isPalindrome(String input1)
{
int j = input1.length();
for(int i=0;i<s.length()/2;i++)
{
char ch= input1.charAt(i);
if(ch!= input1.charAt(j-1))
return 0;
j--;
}
return 1;
}
Test Case:
input1: level
output:
1
5. Max occurring character
private static String maxOccurance(String input1)
{
char[] c=new char[26];
String s="";
for(int i=0;i<input1.length();i++)
{
char ch= input1.charAt(i);
c[ch-97]++;
}
int max=0;
for(int i=1;i<26;i++)
{
if(c[max]<c[i])
max=i;
}
for(int i=0;i<26;i++)
{
if(c[i]==c[max]&&i!=max)
return "0";
}
return s+(char)(max+97);
}
Test cases:
input1 : abcdd
output : d
6. Number Sum
private static int sum(int input1, int[] input2)
{
int max=input2[0];
int min=input2[0];
for(int i=1;i<input2.length;i++)
{
if(max<input2[i])
max=input2[i];
if(min>input2[i])
min=input2[i];
}
return max+min;
}
Test cases:
input 1: 7
input 2: { 7,2,6,15,54,10,23}
output : 56
7. Anagram
private static String isAnagarm (String input1,String input2)
{
int n1 = input1.length();
int n2 = input2.length();
if (n1 != n2)
return "no";
input1=input1.toUpperCase();
input2=input2.toUpperCase();
int a[]= new int[26];
int a2[]= new int[26];
for(int i=0;i<n1;i++)
{
char ch= input1.charAt(i);
a[ch-65]++;
}
for(int i=0;i<n2;i++)
{
char ch= input2.charAt(i);
a2[ch-65]++;
}
for (int i = 0; i < 26; i++)
if (a[i] != a2[i])
return "no";
return "yes";
}
Test cases:
input1:build
input : dubli
output : yes
8. Coin Counts
private static int getcount(int input1)
{
int coin=0;
while(input1!=0)
{
coin=coin+(input1*input1);
input1--;
}
return coin;
}
Test cases:
input1 : 2
output : 5
9. Electro Static
private static int electroStatic(int[] input1, String input2, int input3)
{
int sum=0;
for(int i = 0;i<input3;i++)
{
char ch = input2.charAt(i);
switch(ch)
{
case 'P':
sum=sum+input1[i];
break;
case 'N':
sum=sum-input1[i];
break;
}
}
return sum*100;
}
Test cases:
input1 : {4,3,5}
input2 : PNP
input3 : 3
output : 600
10. Reverse Array
public static int[] reverseArray(int [] input1,int input2) {
int [] ars=new int[input2];
int k=0;
for(int i=input2-1;i>=0;i--)
{
ars[k]=input1[i];
k++;
}
return ars;
}
