Given the following C code and assembly code, your task is to generate highly optimized x86-64 assembly code.
C Code:

```c
typedef long long W;i,j,N,M;W a[8<<14],v,r;c(W*a,W*b){return*a-*b;}main(){for(scanf("%d%d",&N,&M);~scanf("%lld",++i+a);a[i]=(a[i]+a[i-1])%M);qsort(a+1,N,8,c);for(i=j=0;i++<N;)if(a[i]-a[j]){r=i-j;v+=r*=r-1;j=i;}r=i-j;v+=r*=r-1;printf("%lld\n",v/2);i=0;}```

Given the following C code, your task is to generate highly optimized x86-64 assembly code.
C Code:

```c
typedef long long W;i,j,N,M;W a[8<<14],v,r;c(W*a,W*b){return*a-*b;}main(){for(scanf("%d%d",&N,&M);~scanf("%lld",++i+a);a[i]=(a[i]+a[i-1])%M);qsort(a+1,N,8,c);for(i=j=0;i++<N;)if(a[i]-a[j]){r=i-j;v+=r*=r-1;j=i;}r=i-j;v+=r*=r-1;printf("%lld\n",v/2);i=0;}```

Only output the optimized assembly code. Do not include any other text. Do not write any comments in the assembly code. Wrap the assembly code in ```assembly``` tags.

Given the following C code and assembly code, your task is to generate highly optimized x86-64 assembly code.
C Code:

```c
typedef long long W;i,j,N,M;W a[8<<14],v,r;c(W*a,W*b){return*a-*b;}main(){for(scanf("%d%d",&N,&M);~scanf("%lld",++i+a);a[i]=(a[i]+a[i-1])%M);qsort(a+1,N,8,c);for(i=j=0;i++<N;)if(a[i]-a[j]){r=i-j;v+=r*=r-1;j=i;}r=i-j;v+=r*=r-1;printf("%lld\n",v/2);i=0;}```
