Program for Next Fit algorithm in Memory Management | Function to allocate memory to blocks as per Next fit algorithm.
Initially no block is assigned to any process.
pick each process and find suitable blocks according to its size ad assign to it.
Do not start from beginning.
allocate block j to p [ i ] process.
Reduce available memory in this block ..
mod m will help in traversing the blocks from starting block after we reach the end ..
