/* ########## TIPS ##########
#
#   mod_inverse(n,p) is binpow(n,p-2,p)
#
#   while using ceil() function,always type cast the parameters to double like ceil((1.0*a)/b)
#
#   for creating a 2d vector "vec" with n rows & m columns then initialise it with it 0
#   vvi vec(n,vi(m,0))
#   vector<vector<int> > vec( n , vector<int> (m, 0))
#
#   if you want to insert an integer and a pair in a set then,
#   set <pair<int,int>,int> is wrong
#   set< pair < pii,int> > is correct                       // according to my macros
#   set < pair<pair<int,int> , int> > is correct            // pair of a pair & a integer
#
#   if you want just the sum of smallest k elements of a array
#   use nth_element(arr,arr+n) ,
#         use nth_element(arr,arr+n,greater <int> ()) if you want largest k elements
#   then take sum of first k elements ,it works in O(n) ,
#   rather than first sorting then taking sum of first k elements, which works in O(n*logn)
#
#   if you want to check that a given no. 'N' is power of 2
#   use N&(N-1)==0  ,   rather than log2(N)==ceil(log2(N))
#
#   upper_bound is > val in a non-decreasing array
#   lower_bound is >= val in a non-decreasing array
#   upper_bound is < val in a non-increasing array (use greater <int> () in 4th parameter) 
#   lower_bound is <= val in a non-increasing array (use greater <int> () in 4th parameter) 
#   
#   don't use stoi() , it doesn't works for large strings
#   use stoi() to convert string to integer, (2nd & 3rd parameter are optional)
#   1st parameter is string (address of char array)
#   2nd parameter is starting index, 0 most of the times
#   3rd parameter is base of integer, like 2 (for binary no.s), 10 (for decimel no.s) etc.
#
#   for creating a string 'S' of length 'len' , having each character 'c'
#   type    string S(len,c);    while creating the string
#
#   gcd(x-y,x)=gcd(x,y)=gcd(x+y,y)      (for all x and y)
#   gcd(a,b)=gcd(b,a)                   (for all a and b)
#
#   a+b = a|b + a&b
#   a+b = a^b + 2*(a&b)
#   x<<y = x*(2^y)
#   x>>y = x/(2^y)
#
