I need the answers for the following programs

1.       Kindly send the answers for this question i need it by today itself because i am having interview by tomorrow

Write a program to convert a decimal number to hexadecimal without converting it to binary.

2.       Write a program to check whether the given number is a palindrome or not.(without using arrays)

3.       Write a program to find a string and replace it with another string in the given input sentence.

Example:

input sentence:  This is  my pen

word to be replaced: is

word to replace with: was

Output should be: Thwas was my pen

4.       Write a program to calculate LCM and GCD of the given two integers (without function calls).

5.       Write a program to print different rotations of the given input string.

For example:                                   

 input : 4WTECH

Output:

  WTECH4

  TECH4W

  ECH4WT

  CH4WTE

  H4WTEC

6.       Write a program to check whether the given input number is an Armstrong number. (Without using math functions)

Example:

   153=1³+5³+3³

7.       Write a program to display ,                       

1

2 2

3 3 3

4 4 4 4 upto n

(using single loop. Should not use nested loops.Should not use conditional statements like if.

And no function calls should be used)

8.       Write a program to remove duplicates in the given array of integers and do a binary search in that.

Example:

                input- Array(10)={4,5,7,8,8,9,5,5,4,2}

output- Array after removing the duplicates,

                                {4,5,7,8,9,2}

Input- Number to search- 5

Output- Position of  5 is -1

9.       Write a program to delete an element from an array.(using a single array)

10.   Write a program to rearrange the contents of an integer array so that all the odd elements are placed before the even.

Example:

Input-Array(12)={6,23,5,16,78,4,8,7}

Output- Array(12)={23,5,7,6,16,78,4,8}

11.   Write a program to count the number of binary 1's in the given input number

Example

Input – 8

Output -1

12.   Write a program to convert the given input string from lower case to upper case without using in-built functions.
