How do you create palindrome number in core java?

suppose n is a number i.e n=325 First we shall divide that number by 10 then store this number in a variable called quation i.e q=n/10 here q=32 . we take one variable say m and store the value of n in that variable i.e n=m And then we shall find remender of that number by dividing 10 i.e n=n%10 we get 5 then we will reverse that number i.e r=r*10+n and then we will repeate the same step if reverse of that number is same as the number entered then that number is called paindrom code: class palindrom { public static void main(String args[]) { int n,m,s,r; n=m; for(s=0;n>0;) { q=n/10; r=n*10; s=s*10+r; n=q; } if (m==r) { System.out.println("Palindrom"); } else { System.out.println(" not Palindrom"); } } } Wrriten By:-Rajkumar Gupta

nCr + nCr-1 = n!/[r!(n-r)!] + n!/[(r-1)!(n-r+1)!] = n!/[(r-1)!(n-r)!]*{1/r + 1/n-r+1} = n!/[(r-1)!(n-r)!]*{[(n-r+1) + r]/[r*(n-r+1)]} = n!/[(r-1)!(n-r)!]*{(n+1)/r*(n-r+1)]} = (n+1)!/[r!(n+1-r)!] = n+1Cr
