MCMF? solution codeforces

  MCMF? solution codeforces You are given two integer arrays aa and bb (bi≠0bi≠0 and |bi|≤109|bi|≤109). Array aa is sorted in non-decreasing order. The cost of a subarray a[l:r]a[l:r] is defined as follows: If ∑j=lrbj≠0∑j=lrbj≠0, then the cost is not defined. Otherwise: Construct a bipartite flow graph with r−l+1r−l+1 vertices, labeled from ll to rr, with all vertices having bi<0bi<0 on the left and those with bi>0bi>0 on right. For each i,ji,j such that l≤i,j≤rl≤i,j≤r, bi<0bi<0 and bj>0bj>0, draw an edge from ii to jj with infinite …

Palindromic Indices solution codeforces

  Palindromic Indices solution codeforces You are given a palindromic string ss of length nn. You have to count the number of indices ii (1≤i≤n)(1≤i≤n) such that the string after removing sisi from ss still remains a palindrome. For example, consider ss = “aba” If we rem ove s1s1 from ss, the string becomes “ba” which is not a palindrome. If we remove s2s2 from ss, the string becomes “aa” which is a palindrome. If …
