1. Bubble Sort

for i = n down to 1
for j = 1 to i-1
if A[j] < v="Fr0SmtN0IJM&feature="related" and="" an="" unsorted="" x="">= i */
for(i=1;i v ) {
a[j] = a[j-1]; j = j-1;
if ( j <= 0 ) break; } /* Stopped when a[j-1] <= v, so put v at position j */ a[j] = v; } } 3. selection sort Video : http://www.youtube.com/watch?v=TW3_7cD9L1A&feature=channel Selection sort is the most conceptually simple of all the sorting algorithms. It works by selecting the smallest (or largest, if you want to sort from big to small) element of the array and placing it at the head of the array. Then the process is repeated for the remainder of the array; the next largest element is selected and put into the next slot, and so on down the line. The idea of selection sort is rather simple: we repeatedly find the next largest (or smallest) element in the array and move it to its final position in the sorted array. Assume that we wish to sort the array in increasing order, i.e. the smallest element at the beginning of the array and the largest element at the end. We begin by selecting the largest element and moving it to the highest index position. We can do this by swapping the element at the highest index and the largest element. We then reduce the effective size of the array by one element and repeat the process on the smaller (sub)array. The process stops when the effective size of the array becomes 1 (an array of 1 element is already sorted). void selection_sort(int x[], int lim) { int i, eff_size, maxpos, tmp; for (eff_size = lim; eff_size > 1; eff_size--) {
for (i = 0; i < maxpos =" x[i]"> x[maxpos] ? i : maxpos;
tmp = x[maxpos];
x[maxpos] = x[eff_size - 1];
x[eff_size - 1] = tmp;
}
}

swiss trip imp info

http://www.raileurope.co.in/

Why peak at one?
A Swiss Pass will let you travel on scenic rails all over Switzerland, including the Glacier Express with nothing more than a reservation. So think carefully. Is one day trip enough, or is it just the icing on the glacier?

Swiss Pass

Neeraj : not sure if we really need to buy "Glacier Express" if we have swiss pass. i think it free. we must find out this option.

Hi Sherill,

Check this website for Glacier Express and Swiss Pass info:

www.swisstravelsystem.ch/Glacier_Express.31.0.html?&L=2

www.swisstravelsystem.ch/Tickets.16.0.html?&L=2

We went from St. Moritz to Zermatt on the Glacier Express. While
I don't know what 1st class was like, we were quite comfortable
in 2nd class.... except for the loooong trip. It was closer to 9
hours. We did have reservations for the GE trip. We used an 8
day Swiss Pass (2nd class) and were completely satisfied with
our choice on all the trains we used.

good site to compare swiss pass / swiss card / ticket

Try to find what is golden pass train from from Lucerne to Interlaken Ost by Golden Pass Panoramic train.

reserve your seat at the same time when you buy your Swiss Card or reserve your seat through the site of goldenpass.ch
