Here,I fixed it. https://codeforces.me/contest/1005/submission/75775687

You were doing a[k+1] so the upper bound should be k<n-1 not k<n(a[n] wasn't initialized)

for(int k=0;k<n;k++) when k = n-1, it's trying to access the data of a[n] inside if(a[k] >= a[k+1]). a[n] will show a garbage value unless you initialize it.
