DNA is sequence of bases A, G, T, C. Let DNA [a.b] be the subsequence of DNA starting from index a finishing in b inclusive, and DNA[a.] be the subsequence of DNA starting from index a to the end. We could perform the following ops on DNAS: cross operation – they take DNA1 and DNA2 and numbers kl and k2. Then two new DNAS are created: DNA3 = DNA1[1.,k1]+DNA2[k2+1.] and DNA4 = DNA2[1..k2]+DNA1[k1+1..].mutate operation - they take a DNA, number k and one of the bases. Then they replace the base in position k in DNA with that base. also, they need to know certain %3D characteristics of those DNAS. So, they can perform count operation – they take DNA and numbers k1 and k2 (k1 <= k2). This operation should return the number of A, G, T, C bases in DNA[k1..k2].The initial DNAS are numbered from 1 to n, where n is the amount of those DNAS. The new DNAS the first line of input file contains number n- the number of initial DNAS. Each of the following n lines contains the description of each DNA. The next line contains number q- the number of operations to perform. The next q lines contain the description of each operation in the following form: CROSS id1 id2 k1 k2

Question
DNA is sequence of bases A, G, T, C. Let DNA [a..b] be the subsequence of DNA starting from index a
finishing in b inclusive, and DNA[a..] be the subsequence of DNA starting from index a to the end. We
could perform the following ops on DNAS: cross operation - they take DNA1 and DNA2 and numbers
kl and k2. Then two new DNAS are created: DNA3 = DNA1[1,,k1]+DNA2[k2+1.] and DNA4 =
DNA2[1..k2]+DNA1[k1+1..].mutate operation – they take a DNA, number k and one of the bases. Then
they replace the base in position k in DNA with that base. also, they need to know certain
characteristics of those DNAS. So, they can perform count operation - they take DNA and numbers k1
and k2 (k1 <= k2). This operation should return the number of A, G, T, C bases in DNA[k1..k2].The
initial DNAS are numbered from 1 to n, where n is the amount of those DNAS. The new DNAS the first
line of input file contains number n - the number of initial DNAS. Each of the following n lines contains
the description of each DNA. The next line contains number q- the number of operations to perform.
The next q lines contain the description of each operation in the following form:
CROSS id1 id2 k1 k2
MUTATE id k m
COUNT id k1 k2
For each count operation print four integers: the number of each of the bases in the given
subsequence of the given DNA. Use Python Only
Input:
CTCGC
TGCGG
5
MUTATE 12 A
COUNT 224
MUTATE 21G
CROSS 2 115
COUNT 4 36
Output:
0201
0202
