The pseudo code of the string matching algorithm is given below: Note that the pseudo code below tests only for the occurrence (or the absence) of the search pattern in the search string. You will have to slightly modify the pseudo code to count the number of occurrences of the pattern in the string as well as the total number of character comparisons.
ALGORITHM BruteForceStringMatch(T[0..n - 1], P[0..m - 1])
// Implements brute-force string matching
// Input: An array T[0..n - 1] of n characters representing a text and
// an array P[0..m - 1] of m characters representing a pattern
// Output: The index of the first character in the text that starts a
// matching substring or -1 if the search is unsuccessful
for i <- 0 to n - m do
j <- 0
while j < m and P[j] = T[i + j] do
j <- j + 1
if j = m return i
return -1
